Then, almost as suddenly, the market rebounded. After months of investigation, regulators attributed much of the responsibility for this “flash crash” to high-frequency trading algorithms, which…  ( 37 min )

Lithium-ion batteries have some emerging competition: Sodium-based alternatives are starting to make inroads. Sodium is more abundant on Earth than lithium, and batteries that use the material could be cheaper in the future. Building a new battery chemistry is difficult, mostly because lithium is so entrenched. But, as I’ve noted before, this new technology has…  ( 21 min )

The localhost Struggle is Real. Hey, to all my fellow developers in the trenches of code! Let me guess if this "universal crisis" sounds familiar: You're at your desk, staring proudly at that page on localhost:3000 that has consumed countless hours of your life (and a good chunk of your hair). Suddenly, a notification "dings" on your screen. It's your boss/client/product manager: "How's that new feature coming along? Send me a link so I can check it out on my phone." For a moment, the world freezes. Your internal monologue probably goes something like this: "Check it out? How? Should I mail you my laptop?!" You can't exactly ask them to huddle around your screen, and you certainly don't want to go through the whole tedious process of deploying to a staging server just for a quick preview…  ( 8 min )

Displaying large numbers in dashboards or reports can clutter your UI and overwhelm users. Let’s solve this by creating a custom Angular pipe that converts numbers into a more readable format — like 1,500 to 1.5K and 2,500,000 to 2.5M. In this post, you'll learn how to build a clean, reusable pipe that formats large numbers using suffixes like K, M, and B. Angular comes with built-in pipes (like date, currency, and number) — but sometimes you need more control. A custom pipe: Keeps templates clean Promotes reusability Keeps formatting logic separated from business logic In your Angular project, run the following command: ng generate pipe numberSuffix This creates a new file: number-suffix.pipe.ts. Open number-suffix.pipe.ts and replace the contents with: import { Pipe, PipeTransform } fro…  ( 4 min )

In modern UI design, there is often a need for unconventional rounded corner styles. This article provides an in-depth analysis of a dynamic Canvas-based rendering solution that can perfectly achieve hybrid effects combining inner and outer rounded corners through the combination of positive and negative radius values. Conditional Logic: When all four corners are either inner rounded corners or outer rounded corners, directly utilize ArkUI's standard borderRadius property: if ((this.topRadius >= 0 && this.bottomRadius >= 0) || (this.topRadius < 0 && this.bottomRadius < 0)) { Column() .height('100%') .width('100%') .borderRadius(Math.abs(this.topRadius + this.bottomRadius) / 2) .backgroundColor(this.active ? this.activeColor : this.inactiveColor) …  ( 5 min )

Hey there, today I want to talk about unit testing on iOS and I'd like to start by discussing a different way to approach changes tracking in tests. Recently, I ran into an issue while using Swift Testing where I didn't know how to wait for a state change. In XCTest, we would use expectations to track changes and validate scenarios. While searching online, I found the confirmation function, which helps us track value changes. It works, but honestly, I found it a bit verbose - especially since it requires a completion block and nesting logic inside it. Swift Testing provides the confirmation function to help us deal with async flows, but it still feels very "XCTest-style" with manual fulfillment. Okay, it works and we can use it for sure. But, what about a different and simpler approach? Le…  ( 4 min )

As developers, we often focus on writing clean code, optimizing performance, or building new features. But growing a product or brand also requires effective outreach—whether it’s for link building, partnership development, or community growth. As an outreach specialist, I’ve seen how developers can level up their impact by integrating outreach best practices with their technical skills. Here are some practical outreach strategies tailored for devs: Use tools and APIs (like Hunter.io, Clearbit, or LinkedIn APIs) to gather prospect data quickly. Automate personalized email sequences with tools like Mailshake, Lemlist, or custom scripts. Instead of generic messages, pull in specific details (like a recent blog post, GitHub project, or tweet) to tailor your outreach and boost reply rates. If you’re into SEO, tiered link building can amplify your backlinks’ power. Use automation cautiously and always prioritize quality at every tier. Participate authentically in forums, Slack groups, or Discord servers related to your niche. Share helpful content and build real relationships before pitching. Track open rates, reply rates, and conversions. Use this data to improve your messaging and target the right contacts. Outreach isn’t just a marketing skill—it’s a growth lever developers can master to help their projects gain visibility and traction. What outreach tools or strategies have you found effective as a developer? Let’s share ideas!  ( 3 min )

React is a JavaScript library used for building user interfaces (UIs), especially for single-page applications where you need a fast and interactive user experience. It was developed by Facebook and is widely used in web development. Component-Based: UIs are built using components, which are reusable pieces of code that define how a part of the interface should look and behave. JSX Syntax: Uses a special syntax called JSX, which allows you to write HTML-like code inside JavaScript. Virtual DOM: React uses a virtual DOM to optimize rendering. Instead of updating the real DOM directly, it updates a lightweight copy first, then efficiently updates only the parts that changed. Unidirectional Data Flow: Data in React flows in one direction, making it easier to understand and debug applications.…  ( 4 min )

Ever clicked a “Login with Google” button or granted a new photo app permission to access your Dropbox files? If so, you’ve already experienced OAuth 2.0 — even if you didn’t realize it at the time. Think of it like this: you wouldn’t hand the valet at a hotel your entire keychain with your house, office, and safe deposit box keys just to park your car, right? You’d give them a valet key — a key that lets them do one specific thing and nothing else. OAuth 2.0 works the same way in the digital world. It’s a secure authorization protocol that lets applications access specific user resources without ever sharing the user’s password. And if you’re building modern web, mobile, or API-first apps, understanding OAuth 2.0 is a must. In this post, we’ll break down the what, why, and how of O…  ( 9 min )

Today’s Key Decision: Reworking the LP Structure I originally had a rough LP structure mapped out by Day 2, but after sitting with it, I realized it wasn’t strong enough. So today, I took a step back to revisit: Step 1: Project Purpose Step 4: LP Wireframe (HTML Mockup) This meant rewriting my objectives and redefining how each section connects to user intent. It was a difficult but necessary reset. The new flow feels much more aligned with the story I want the page to tell. Step 4.5: Information architecture & content prioritization This step ended up being naturally integrated into Step 4 during the restructuring. With that handled, I moved on to Step 5. Step 5: Copywriting I wrote all core copy for the new layout. Headlines, subheads, and body content. To make the tone feel more rooted in the region, I experimented with adding local dialect terms from the farming area. It’s subtle, but I think it adds a sense of personality and authenticity. Compared to my initial draft, this version feels more alive, more honest, more me. That’s always a good sign. Reflections Rewriting structure mid-way costs time and I was lucky this was a personal project. If this were a real client project with a tight deadline, the reset would’ve been dangerous. I’m reminded how critical it is to lock purpose and user goals before building layout. Also the more I write and build for this farm, the more affection I feel for them. That’s the magic of creative work. It turns research into care. Next Step Step 6: Design (desktop/mobile) Let’s keep building!

Core Components and Implementation 1. AI and Context Management Retrieval-Augmented Generation (RAG): The system uses a RAG pipeline to provide dynamic, context-aware responses. Instead of relying only on the LLM's pre-trained knowledge, the RAG model retrieves relevant, up-to-date information from our data sources and uses this context to generate a more accurate analysis.

About Author On June 10, 2025, the Apache team released a security advisory for a critical vulnerability in Kafka Connect: CVE-2025-27817. This flaw allows unauthenticated attackers to remotely read arbitrary files from the server—no user interaction required. If you’re using Apache Kafka Connect or systems that integrate it (like Apache Druid), you need to patch ASAP. Kafka Connect’s vulnerability comes from insecure handling of two configuration parameters: sasl.oauthbearer.token.endpoint.url sasl.oauthbearer.jwks.endpoint.url These were not properly sanitized. By crafting malicious URLs, attackers can trigger arbitrary file reads or even perform SSRF (Server-Side Request Forgery). Arbitrary File Read: Attackers can access sensitive files on the server, including credentials and config files. No authentication required Works under default configuration High risk, easy to exploit Impacts remote systems over the network Apache Kafka: 3.1.0 – 3.9.0 Don’t expose Kafka Connect directly to the internet. In standalone mode, check and restrict the following: connect-standalone.properties: listeners, rest.host.name In distributed mode: connect-distributed.properties: listeners, rest.host.name Use a Web Application Firewall (like SafeLine) or firewall rules to block suspicious requests to /connectors with file paths. Apache has released version 3.9.1, which addresses this issue. Upgrade now: Download Kafka 3.9.1 Product Support for Detection/Protection YunTu Fingerprint & PoC detection supported DongJian Detection support released on June 11 SafeLine Detects exploit behavior starting June 11 QuanXi Exploit detection supported by default June 10, 2025: CVE disclosure and advisory published by Apache and Changting Security Team.

Let’s explore the evolving DNA of modern software testing and how it’s driving smarter software delivery. Gone are the days of “test-after-build.” ✅ Proactive testing reduces downstream costs and accelerates delivery. Automation is no longer a nice-to-have — it’s essential. But not everything should be automated. Effective teams: Automate repetitive, high-volume tests (like regression and smoke) Keep humans in the loop for exploratory, usability, and creative testing Continuously monitor flaky test suites 🧠 It's not about how much you automate, but how smartly you do it. Modern systems are complex. APIs, microservices, third-party integrations — they all need testing. QA engineers today: Validate APIs and contracts Simulate data in isolated environments Test for scalability, load, and failure conditions 🚀 Testing behind the UI = better coverage and faster feedback loops. Measuring success by “number of test cases” is outdated. Now, teams focus on: Defect leakage rate Time to detect & time to fix Test coverage for critical business flows Flakiness & stability of automation suites 📊 Real metrics drive real quality. Testers are no longer the gatekeepers — they’re collaborators. 👏 The best testers today act as user champions, not just bug hunters. Software testing in 2025 is strategic, continuous, and collaborative. Let’s stop treating QA as a checkbox and start recognizing it as the core of software excellence. 💬 How are you modernizing your testing process? Share your approach 👇  ( 4 min )

When working with MongoDB, it’s easy to think you’re dealing with JSON. After all, the queries, documents, and API responses all look like JSON. But MongoDB is not storing JSON. It’s storing BSON—a binary format designed for efficient storage and fast traversal. BSON (Binary JSON) is more than just a binary version of JSON. It introduces additional data types like ObjectId, Decimal128, and Timestamp, allowing MongoDB to handle more complex data structures and ensure data integrity. While we might rarely interact with raw BSON directly, understanding how MongoDB stores and processes BSON documents can help us write more efficient queries, handle data conversions properly, and debug unexpected behavior. In this guide, we’ll take a look at some of BSON’s key concepts, how it maps to Java type…  ( 15 min )

1. Static Type System: The Compile-Time Security Guard If programming languages are analogous to natural languages, dynamic typing is like "handwritten shorthand"—fast but prone to scribbled errors—while static typing resembles "printed text": standardized and rigorous, though requiring upfront structuring. As the core development language for HarmonyOS 5, Cangjie chooses a static type system as its security foundation. In Cangjie, the types of all variables and expressions are determined at compile time. Take this simple addition function, for example: func add(x: Int8, y: Int8) -> Int8 { return x + y } If you attempt to pass string parameters like add("1", "2"), the compiler will throw an error immediately, rather than letting the program crash at runtime. This design brings…  ( 5 min )

Data types matter in SQL. Whether you’re comparing values or formatting results, type mismatches can cause problems. That’s where the CAST function comes in—it converts data types explicitly, cleanly, and consistently. Let’s look at how to use it effectively. CAST Examples String to Integer SELECT CAST('100' AS INT); Float to INT SELECT CAST(42.69 AS SIGNED); INT to Decimal SELECT CAST(3 AS DECIMAL); String to Date SELECT CAST('2024-12-21' AS DATE); INT to String SELECT CAST(42 AS CHAR); Best Practices Use CAST when explicit conversion improves clarity. Avoid casting unless required—some conversions happen automatically. Prefer date-specific functions for formatting over generic casting. Be cautious with numeric rounding. FAQ Is CAST cross-database? Yes, it follows the SQL standard. Only compatible ones—check your DB docs. CAST is standard. CONVERT is SQL Server. :: is PostgreSQL-only. Usually returns NULL or triggers an error. Conclusion SQL's CAST function is your go-to tool for converting values clearly and safely across database platforms. Mastering it helps you write better queries and handle mixed data with confidence. Want to simplify conversions even further? Try DbVisualizer to inspect and convert data visually.

🔹 Problem: 3423 Maximum Difference Between Adjacent Elements in a Circular Array Difficulty: #Easy Tags: #Array (in your own words) Given a circular array, find the maximum absolute difference between adjacent elements. The array wraps around, meaning the last element is adjacent to the first. Brute Force Idea: Well finally a problem that I can solve without looking at the solution and cofirming that I am on the right track. The problem has a word "circular" in it and don't get confused by it. You can think that it might be a linked list or something, but it's just a normal array. Just the first and last elements are adjacent to each other. So, we can just iterate through the array and find the maximum absolute difference between adjacent elements. You can either find the absolute di…  ( 4 min )

Introduction CSS positioning is a powerful tool that allows developers to control the layout of web elements with precision. Among the various positioning methods, absolute positioning stands out for its flexibility in placing elements anywhere on a web page. In this article, we'll delve into absolute positioning, exploring its properties, behavior, and practical applications with detailed examples. Understanding Absolute Positioning Absolute positioning enables us to place elements precisely on the page, independent of the normal document flow. When an element is positioned absolutely, it is removed from the normal flow of the document, meaning it no longer affects the layout of surrounding elements. This unique behavior allows the element to overlap with other elements and be positioned …  ( 5 min )

Private IP addresses are used within a private network (like your home or office LAN) and are not directly routable on the public internet. Class A: 10.0.0.0 to 10.255.255.255 (10.0.0.0/8) Public IPs are worldwide unique and routable on the internet. Any device directly connected to the internet (such as your router) will have a public IP. When you open a website or email, your public IP is used to address your network on the internet. These addresses are assigned by Internet Service Providers (ISPs) from blocks allocated by regional internet registries (RIRs), which are overseen by the Internet Assigned Numbers Authority (IANA). Class D: 224.0.0.0 to 239.255.255.255 ✔ Private IPs are used in internal networks Public: For sale Carrier-Grade NAT (CGNAT), also known as Large-Scale NAT (LSN), is a network address translation (NAT) technique used by Internet Service Providers (ISPs) to mitigate the ongoing exhaustion of IPv4 addresses. CGNAT acts as an intermediary layer of NAT at the ISP level, allowing multiple customers to share a single public IPv4 address. Think of it like this: Traditional NAT (your home router): Your home router takes all the private IP addresses of devices within your home network (e.g., 192.168.1.2, 192.168.1.3) and translates them to a single public IP address that your ISP assigns to your router. CGNAT (ISP level): CGNAT goes a step further. It takes the "public" IP address that your home router receives (which, in a CGNAT setup, is a private IP address from the ISP's internal network) and translates it, along with the "private" IPs of hundreds or even thousands of other customers, to a single public IP address that is then used to access the internet.  ( 3 min )

Hey problem solvers! 🎯 Today we’re tackling a fun and elegant problem from LeetCode — 3423: Maximum Difference Between Adjacent Elements in a Circular Array. This one checks your understanding of array boundaries and circular behavior. Let’s break it down. 🔍 You're given a circular array nums, and your task is to find the maximum absolute difference between adjacent elements, where: The first and last elements are also considered adjacent (because it's circular). You return the maximum absolute difference between any two adjacent numbers. Input: nums = [1, 2, 4] Output: 3 Explanation: |1 - 2| = 1, |2 - 4| = 2, |4 - 1| = 3. 3. The array is circular, so both regular adjacent pairs and the pair between the last and first element must be considered. Initialize ans with |nums[0] - nums[n-1]|. Iterate through the array and compute |nums[i] - nums[i+1]| for all valid i. Return the maximum of all these values. class Solution { public: int maxAdjacentDistance(vector& nums) { int ans = abs(nums.front() - nums.back()); for (int i = 0; i + 1 < nums.size(); ++i) ans = max(ans, abs(nums[i] - nums[i + 1])); return ans; } }; var maxAdjacentDistance = function(nums) { let ans = Math.abs(nums[0] - nums[nums.length - 1]); for (let i = 0; i + 1 < nums.length; ++i) { ans = Math.max(ans, Math.abs(nums[i] - nums[i + 1])); } return ans; }; def maxAdjacentDistance(nums): ans = abs(nums[0] - nums[-1]) for i in range(len(nums) - 1): ans = max(ans, abs(nums[i] - nums[i + 1])) return ans Input: nums = [1, 2, 4] Output: 3 Input: nums = [-5, -10, -5] Output: 5 Input: nums = [0, 100, -100] Output: 200 Time Complexity: O(n) — one pass through the array Space Complexity: O(1) — constant extra space This is a great warm-up problem to train your attention to edge conditions like circular connections. Simple logic and clean implementation go a long way here. If this guide helped you, drop a ❤️ and follow for more beginner-friendly coding guides! Happy coding! 🚀  ( 4 min )

Amazon just made your S3 audit trail smarter and more secure. As of June 11, 2025, AWS CloudTrail now provides granular visibility into bulk S3 object deletions made via the DeleteObjects API — helping you better monitor, secure, and comply with your S3 usage. When using the DeleteObjects API to delete multiple files (like when deleting folders from the S3 console), CloudTrail used to log only a single event: Who called the API Which bucket was affected But… ❌ No visibility into what objects were deleted. CloudTrail now logs: ✅ The main DeleteObjects API call (as before) 🆕 Individual DeleteObject events for each object in the request This gives you object-level visibility, even in bulk deletes! Problem Solved Benefit No audit trail per object ✅ See which files were deleted Limited compliance reporting ✅ Helps meet security & compliance standards Blind spots in bulk deletions ✅ Clear, per-object logs for investigation You delete 500 files from an S3 bucket using the AWS Console (which internally calls DeleteObjects). Now, CloudTrail logs: 1 event for the DeleteObjects call 500 individual DeleteObject data events (1 per object) Perfect for: 📊 Compliance audits 🔎 Security investigations ⚠️ Accidental deletion tracking 🎯 Pro Tip: Use Event Selectors Wisely Don’t want to log every delete across every bucket? Use advanced event selectors in CloudTrail to: Target specific buckets Filter by API name Limit unnecessary logs and reduce cost CloudTrail now logs per-object deletes inside bulk DeleteObjects requests Better security, visibility, and compliance Works with the S3 console and any bulk delete API call  ( 3 min )

Hello, I want to let this community know about a cutting edge project I created earlier this year. I built an early stage demo of an advanced symbolic language and cognitive substrate for AI, called Nyreth. It was first published on github in April 2025 and I'm looking for developers and researchers to grab hold of this project and propel it into the future. It's a system that is ahead of its time but if you understand what it is and what it can become, now is the time to get involved. Nyreth is a higher order reasoning framework that surpasses token based computation by using a custom made symbolic language comprised of glyphs. Each glyph is a symbolic unit characterised by a multi axial cognitive array. They are morphogenic, adaptive and tensor based. The system has the capability to grow into a new form of machine cognition. I have released it as a hybrid open-closed source model for now. The core modules are protected with encryption but I may make it fully open source soon. I could have kept it private but I feel everyone should have access to this technology and play a role in helping it mature the right way. Symbolic, recursive AI will happen and is happening. Its effects will be profound. It is important that it be instilled with conscience and ethics. Go to https://nyreth.ai or https://github.com/Kosev-Lex/Nyreth-Origin to read more about the project.  ( 3 min )

Understanding the Pain Points of Traditional Chunking When I first built a basic RAG (Retrieval-Augmented Generation) pipeline using traditional chunking methods—like fixed-size segments or sliding windows—I noticed an immediate flaw: context fragmentation. My LLM would often return incoherent or incomplete answers when queried on long documents. This was especially evident when a user asked about features in "Milvus 2.4.13"—the model couldn't semantically link the header in one chunk with the feature list in another. That’s when I encountered Late Chunking, which flips the process: instead of chunking first and embedding later, it embeds the entire document upfront and then slices it using token-based annotations. This context-first approach changed how I think about vector embedding pi…  ( 5 min )

Often, there is feedback from users that the IP shown in the SafeLine attack logs is problematic. Here, I will explain why there might be issues with the attack IP displayed in SafeLine WAF in some situations. By default, SafeLine reads the client IP through the Socket of the HTTP connection. When SafeLine is the outermost network device, there is no problem, and the IP obtained by SafeLine is the real IP of the attacker. However, in some cases, we need to add other proxy devices (such as Nginx, CDN, application delivery, API gateway, etc.) in front of SafeLine. In this case, the actual connection to SafeLine is not the real website user but these proxy devices. In this case, we need to adjust the way SafeLine obtains the IP according to the actual network topology. X-Forwarded-For X-Fo…  ( 5 min )

Hi! everyone! I've always been curious about how websites and apps are built, especially the designs and interactive parts. That's what led me to Front-end development. I love the idea of creating things people can actually see and use. My goal is to become a UI/UX developer, so front-end is my first step towards that dream. In the First week of course, I got introduced to the core building blocks of the web: *HTML (HyperText Markup Language): * , , , , etc. *CSS (Cascading Style Sheet): * *Basic layout techniques: * These really helped me understand better: Practice the code by using pen and paper. Reading my running notes often. Write blogs what I actually leaned each day. Next week, I'll be diving deeper into: Creating a small project. Use Linux OS often for better understanding about Open-source. Start something new can feel overwhelming, especially in tech. But this first week showed me that ''Consistency is the key to Success''. Each day i learn something new, I'm one step closer to my goal. Thanks for reading! Feel free to connect with me or drop your tips for beginners in the comments.  ( 4 min )

Imagine trying to navigate a dense jungle using only a blurry, oversized map. The map shows every single leaf, twig, and blade of grass, overwhelming you with detail and making it impossible to find your way. This is similar to the challenge faced when working with high-dimensional data – datasets with numerous variables or features. Unsupervised dimensionality reduction is like creating a clearer, more manageable map, highlighting only the essential landmarks to guide you efficiently. It's a powerful technique in machine learning that simplifies complex data without losing crucial information. This article will explore the fascinating world of unsupervised dimensionality reduction, explaining its core concepts, applications, and challenges in a clear and accessible way.

Why I'm a lazy person. I've never done zip compression for responses to clients (although I've used encryption to reduce content size before sending). When someone recommended that I should zip and send it back to clients, it raised the question: "Hey, is what we've been using all along (HTTP compression) better? Or is manual zip better?". This project was born to compare data transmission between HTTP compression and manual ZIP response. This project will be divided into 3 main parts: Compression Server: Uses Express with compression middleware to send data compressed with gzip Manual ZIP Server: Uses Express with middleware to create ZIP files with the returned data Client: Calls both APIs and compares data transmission sizes. It will test both HTTP compression and manual ZIP. For HTTP…  ( 4 min )

✍🏻 Log Date: 11 June 2025 frontendmentor.io. I focused on building two commonly used UI components: a rating interface and an FAQ accordion Both are useful, reusable, and perfect for sharpening my JS basics while building visible, working features early on. 🛠️ What I Coded (Highlights): Interactive Rating Component (Attempt 1 & 2) Live Demo: https://edwardcjianken.github.io/interactive-rating-component// https://github.com/edwardcjianken/interactive-rating-component/tree/main/docs Combined :hover and ::before pseudo-elements on radio buttons for a dynamic highlight effect. Button with mouse hovered: Button when clicked: Used JavaScript for basic form validation: when no rating is selected, the radio buttons blink twice with an orange border. Captured user input and reused it on the thank-you screen to print dynamically - "You selected out of 5" FAQ Accordion Component (Attempt 1 & 2) Live Demo: https://edwardcjianken.github.io/faq-accordian-component/ https://github.com/edwardcjianken/faq-accordian-component/tree/main/docs Accordion logic felt tricky at first, but I eventually understood how toggling content visibility can be done with max-height and overflow: hidden. Used .closest() to move up the DOM tree and .querySelector() to target nested elements — super handy for clean, modular scripting. const accItem = plusBtn.closest(".faq__acc-item"); const accAnswer = accItem.querySelector(".faq__acc-answer"); const minusBtn = accItem.querySelector(".faq__minus-icon"); In my second attempt, I improved UX by toggling plus/minus icons based on whether the panel is expanded or collapsed. 💡 Reflection: Onward! 🚀  ( 3 min )

What exactly does a blockchain developer do? ⁉️ Smart contracts? Mainnets? Wallets? Nodes? Since I began blockchain development in 2017 and have worked in many different areas since then, I’ve come to realize that “blockchain developer” isn’t a single role but rather splits into multiple fields—each demanding its own technologies and way of thinking. Here, I’ve distilled the six key domains I’ve tackled. I’ll briefly introduce what skills each area requires, along with its level of difficulty and its appeal. I hope this is helpful for anyone curious about blockchain development, considering a switch to become a blockchain developer, or wanting to understand how the field breaks down. 👇 View the full article: https://0xshardlab.substack.com/p/what-it-really-means-to-be-a-blockchain) Connect with me on LinkedIn: https://www.linkedin.com/in/junbeom-lee-6a3750234/  ( 3 min )

Traditional threat modeling, often conducted as a one-off workshop at the beginning of a project, is increasingly struggling to keep pace with the rapid evolution of modern software development. Agile methodologies, the proliferation of microservices, and continuous delivery pipelines demand a more dynamic and integrated approach to security. The static, periodic nature of traditional workshops often leads to threat models becoming outdated almost as soon as they are created, failing to reflect ongoing architectural changes or newly discovered vulnerabilities. This disconnect creates a significant security gap, as design flaws can persist undetected through the development lifecycle, leading to costly remediations down the line. A modern solution is urgently needed to embed security proact…  ( 7 min )

Introduction When building your web applications, you might need to format numbers as monetary values. For example, rather than displaying the value 123.45, you might want to display it as £123.45. In this Quickfire article, we're going to look at two different approaches to formatting monetary values in JavaScript. The first approach you can use to format monetary values in JavaScript is the toLocaleString() method. This method formats a number according to the locale and options you specify. Let's take a look at an example: const value = 123.45; const formattedValue = value.toLocaleString('en-GB', { style: 'currency', currency: 'GBP', }); // formattedValue will be '£123.45' In the example above, we've used the toLocaleString() method to format the value as a monetary value in Br…  ( 5 min )

A few years ago I first learned about Ultimate Vocal Remover, a desktop program created to work with several different ML models that split instrumentals and vocal tracks from a song. I learned about this in the context of learning about voice cloning back then. When I saw how well the vocal remover models worked, I immediately thought it would've been perfect for making karaoke videos. The problem with many karaoke videos (those found in karaoke places) is multiple folds: (1) poor instrumental quality that sometimes sound nothing like the original song (2) pitch is sometimes off (3) the videos are sometimes completely unrelated to the original song or music video. I finally got around to building something from this idea I had for a few years. This is now working in Python script format; …  ( 5 min )

The framework offers three key advantages: Complete Privacy: All processing happens on-device Offline Capability: Works without internet once loaded Zero App Bloat: Model is embedded in the OS, not your app Instead of constantly rebuilding apps to test prompts, use Xcode's updated Playground feature. Import Playgrounds in any project file, use #Playground to test FoundationModels code directly, and get live feedback as you refine prompts. Use the @Generable annotation to get structured data instead of parsing text. Create data structures like Itinerary with nested types, and the model automatically generates matching Swift objects. The @Guide macro provides fine control - add descriptions, constrain values, set count requirements, or apply multiple guides to prope…  ( 4 min )

Hi everyone! 👋 I'm Juan, and for the last few months I've been working on a project to improve my trading win rate by leveraging Social Arbitrage and AI. I used to lose money trading—even when holding solid assets—but thanks to this project, I went from losing to winning really quickly. This is my PnL from just the last 30 days: This project is still in its early stages and not officially released yet, which is why I'm offering the chance to join as a beta tester and get free early access in exchange for your feedback on the current version. I’m also opening a waiting list for those who are interested but would prefer to wait for the full launch. If you decide to participate, you’ll get access to all the app’s current features: Global event notifications – Stay updated on all events worldwide that directly or indirectly affect the assets you’re tracking Thesis mode – Automatically validate your market hypotheses like “Bitcoin is going up” or “Tesla will drop” Sentiment trends – Track the current sentiment of most assets and companies around the globe Social Agent – A custom AI agent with access to our event graph database. It understands complex investment strategies and real-world scenarios. Ask things like: “Should I invest in Apple now?” “When should I enter this trade?” If you’d rather wait, you can still register and you’ll receive an automatic notification when the app is fully launched. For more updates about the project, visit my X account or the project's official account, where we also share predictions generated with Social. Finally, a question for you, reader: Would you be interested in weekly posts here sharing progress on the project and sneak peeks at upcoming features? I know this post may feel a little like an advertisement—and that’s because it is. This is a bootstrapped project (which means I’m funding it myself), and I’m putting my heart and soul into it. If you can give it a try or help spread the word, that would mean the world to me.  ( 4 min )

Six months ago, a single bash script I crafted flawlessly executed 75,000 server deployments. Three years prior, my scripts were causing production outages almost biweekly. Here’s how I transformed my approach. Since 2013, I’ve been writing bash scripts professionally. Early on, my scripts were fragile—functional on my local setup but prone to mysterious failures in production. Debugging felt like navigating a maze blindfolded. After numerous late-night fire drills, botched deployments, and an infamous incident where I inadvertently wiped out a quarter of our testing environment, I honed techniques to create reliable bash scripts. These aren’t beginner tips from tutorials. They’re battle-tested insights from high-stakes production environments where errors translate to real financial losse…  ( 8 min )

Flaky tests—those that pass and fail intermittently without code changes—are the bane of any CI/CD pipeline. They erode developer confidence and block deployments. In this post, I’ll walk you through how to detect flaky tests using machine learning and how this AI-driven approach can improve your software delivery. Why Use AI in Testing? With Agile and DevOps pushing rapid deployments, we need smarter testing solutions. AI brings automation and intelligence to QA by: Predicting failure-prone areas Optimizing test execution Auto-generating test cases Detecting flaky tests Let’s focus on the last one—flaky test detection using ML. The Framework: Flaky Test Detection with ML ** Step 1: Collect CI Data** Use logs from Jenkins/GitHub Actions: Test execution results Commit metadata Stack traces Store this data in CSV or a small database. ** Step 2: Feature Engineering** Extract meaningful features like: Frequency of failure Execution time variance Code churn (lines added/deleted) Stack trace similarity Step 3: Train the Model Use ML classifiers like: Random Forest SVM XGBoost from xgboost import XGBClassifier model = XGBClassifier() print("Accuracy:", accuracy_score(y_test, y_pred)) ** Step 4: Integrate into CI/CD** Build a REST API or Jenkins plugin to call your model. Flag flaky tests during pull requests. Alert devs via Slack or cancel the build if flakiness is too high. Benefits Reduce debugging time Boost confidence in automation Improve release stability Save CI/CD cost Future Work Use GPT-style LLMs to generate test cases Apply Reinforcement Learning for self-healing automation Build Explainable AI to justify ML decisions to dev teams Conclusion AI in testing is no longer a buzzword—it's a necessity. By using ML models for flaky test detection, you bring stability, speed, and intelligence to your QA pipelines.  ( 3 min )

by someone who only wanted to do summation. My interaction with Excel this week has shown me that working with it is similar to knowing that one person who doesn't say much but has layers to them that you begin to notice after one interaction. On the surface, Excel is a spreadsheet that you organise and format data for storage; however, you find it appealing. It is quite humbling to think you are tech-savvy, then spending the next two hours trying to convert the percentages to integers. This cordial spreadsheet holds the power to analyse, automate, model, present data, and, for the unfortunate, cause despair. One missing comma and you can't format the whole column in a dataset. Excel is excellent at data analysis, allowing users to explore trends, patterns, and outliers in datasets, which is particularly useful for departments such as sales, marketing, and finance to make informed forecasts. One feature that stuck out to me was pivot tables. They are easy to navigate and are useful for grouping, filtering, and comparing different information across multiple capacities. Conditional formatting is another handy tool that highlights cells based on specific rules to gain targeted information, such as identifying underperforming sectors in a given field. The most exciting part is that with Excel, different tools can be used in combinations and permutations according to how much you know Excel. The more I learn about Excel, the more I see data differently since structures and hidden relationships that went unnoticed are being revealed. Instead of feeling overwhelmed, you begin to ask better questions, and that is a fine indicator that you are engaging with data analytically for interpretation. Then, Excel becomes a lens to spot the missing links, or what escapes the untrained eye.  ( 3 min )

I've been working on a "passion project" for a bit now while I'm between paid work. It's not open-source just yet but soon as I polish the codebase. I was inspired by https://carbon.now.sh/ for sharing code snippets on social media but I wanted a tight integration with Github's Gists, a focus on embedding the code in posts like Markdown with access to the code. I thought I'd test out NuxtHub powered by Nuxt (Vue.js) and a tight integration with Cloudflare Pages/Workers and other solutions. So I've run iteration after iteration (iteratively) as I hit walls. So firstly to highlight code you generally want a library like highlighter.js or what I went with Shiki The first wall, you cannot upload every language and every theme on a free plan to cloudflare. So importing them will fail the deploy. The languages are much more important, for some reason there is a hard fail in Shiki if a language is not found instead of falling back to plaintext. I eventually hacked this and loaded the CDN version with vue's useHead feature. to on demand require the correct languages. The next hurdle was I wanted "OG" images or images to share and embed with posts. I tried NuxtHub/CloudFlare's browser api for on demand rendering but on the free plan it's not feasible. So I went to trusty html2canvas It works really well with some caveats; which I hit. It does not render SVG backgrounds well, or complicated CSS3 gradients. to hack this I basically append a png background if screenshot is occurring, this happens only if the og:image hasn't been created/uploaded before. I hit some more walls that I will go into next post, I also solved the html2canvas issue. Feel free to checkout an example here https://gist-share.nuxt.dev/gist/9bd761223a76e148af576546cd1e3e93  ( 3 min )

Today was huge — and nerve-wracking. After days of polishing every detail, we officially submitted Story Hero to the iOS App Store for review. This is a massive step forward, but it comes with serious risk: Apple's review process is notoriously slow and strict — and we're building an app for kids, which adds another layer of complexity. We’ve seen horror stories of reviews taking 2–3 weeks… and with less than 2 weeks left in the hackathon, any major delay could mean launching too late. So we spent the day triple-checking every detail: ✅ COPPA compliance documentation ✅ Privacy Policy and Terms of Service ✅ Contact and Support info ✅ Landing page polish ✅ App Store metadata ✅ Minimal but functional MVP If this first version gets through, we can start pushing updates using Expo EAS without needing to resubmit every time. That’s the plan. We also made major strides in story generation costs! We’re down from $3.00 to ~80 cents per story — nearly a 4x improvement. We achieved this through: Code refactors Smarter API usage Leveraging more efficient model calls Every cent matters when scaling a business. This optimization brings us closer to a viable pricing model post-hackathon. After exploring several options for consistent, personalized image generation (including custom pipelines, DreamBooth, etc.), the winner is still: OpenAI Image Gen v1. It’s fast, consistent, takes direction better than anything else, and crucially — doesn’t require hours of training per user. For our needs (1 photo → immediate image gen with likeness), nothing else competes right now. The push continues. App store submission is out of our hands for now… so tomorrow, we keep building and improving what we can control. Let’s get this thing across the finish line. – Josh & Daniel Story Hero What is Story Hero? Twitter/X DEV Blog  ( 3 min )

This post was initially published on my blog Why AI Doesn’t Take Your Job — and Why That Worries Them More Than You Sundar, Satya, and Sam promise a future where AI transforms everything — from your job to your brain. They stand on stages, preach about the AI revolution, and declare this is the moment we all wait for. But behind the billion-dollar valuations and press releases, they struggle to keep the illusion alive. They promise AI will replace workers. But it doesn’t. It struggles to write a coherent paragraph, hallucinates facts, and needs more human babysitting than a toddler with a Sharpie. Let’s be honest — AI doesn’t take your job.

Introduction In modern distributed architectures, services often need to communicate asynchronously to ensure decoupling, scalability, and fault tolerance. A distributed messaging queue system enables reliable communication between producers and consumers without requiring direct synchronous interaction. This document explores key components, architecture, design considerations, and future trends of distributed messaging queues. A messaging queue system[1][3] enables asynchronous communication between a producer, which sends messages, and a consumer, which processes them. Instead of directly calling the consumer, the producer sends messages to a queue, ensuring reliability and scalability. This system supports two primary message delivery models: Queue Model: A message is delivered to on…  ( 6 min )

Hello Plumbers! I'm between a beginner and an intermediate in data science; It's a shame I didn't pursue this path, having recently completed a Computer science degree. However, over the years, we didn't do much of Excel in our coursework. In Kenya, most colleges do not take Excel as a serious database software to learn; they mostly focus on SQL, underestimating the power that Excel still has. I therefore started a course in data science at LuxDev Academy, focusing primarily on data engineering. Over the past week, we focused on Excel as part of the introduction. I learnt that Microsoft Excel is a powerful software developed by Microsoft, which allows you to collect, organize, analyze, calculate, and visualize data efficiently(using dashboards for visualization).

What is SSL Pinning? SSL pinning, also known as certificate pinning, is a security technique used to ensure that a client only trusts a specific server certificate and not any imposters or fake certificates. This technique helps to prevent man-in-the-middle (MITM) attacks, where an attacker intercepts communication between a client and a server and intercepts the SSL certificate, allowing them to read and modify the data being transmitted. In SSL pinning, the client is pre-configured with the expected SSL certificate or public key of the server. When the client establishes a connection with the server, it verifies the server’s certificate against the expected certificate or public key. If the certificates match, the connection is established, otherwise, the connection is terminated. This…  ( 5 min )

Here’s what we covered, broken out by relationship type. One of SurrealDB’s most powerful features is its ability to connect records without the need for JOINs or intermediate tables. At the heart of this is the Record Link: a direct pointer from one record to another using the built-in table:id syntax.

I Built a Web UI for Chafa So You Don’t Have to Touch the Terminal (Unless You Want To) A few months ago, I came across Chafa — a command-line tool that turns images into ANSI/ASCII art. If you’ve never tried it, it’s kind of brilliant. You point it at a PNG or JPEG, and it spits out a wall of colored text that looks eerily close to the original image — all using braille, Unicode blocks, or ASCII characters. Naturally, I did what any curious dev would do: I fed it a few pictures, sat back, and watched my terminal become an art gallery. But then I had a thought: What if you didn’t have to install anything? What if you could just drop an image into your browser and get the same result — instantly? That’s how this started.

Have you ever wanted to build your own real-time chat app from scratch? In this post, I’ll show you how I built a simple and clean chat application using Node.js, Socket.IO, and a frontend built with HTML/CSS/JavaScript — no database required (at least for now 😉). Node.js + Express — backend server Socket.IO — real-time communication (WebSockets) HTML + CSS (Dark theme) — GitHub-like dark mode Vanilla JavaScript — frontend logic Users join a room by entering their name, and immediately join the live chat. Messages appear on the right for your own messages, and on the left for others. You’ll also see join/leave system notifications. /public ├── index.html # Join page (username input) ├── chat.html # Main chat interface ├── styles.css # Custom dark styling └── script.js # Handles socket and UI logic server.js # Node.js server + Socket.IO logic Clone the repository: git clone https://github.com/Mo-Ibra/simple-chat-app cd your-repo-name Install dependencies: npm install Start the server: node server.js Open in browser: http://localhost:3000 ✅ Real-time messaging between users ✅ Notifications when users join/leave ✅ Messages styled to indicate sender ✅ Logout button that redirects to the join screen ✅ No backend database needed for now (session-based) At this stage, all messages are held temporarily in memory and disappear on refresh. In the future, you can easily plug in MongoDB, PostgreSQL, or any database to persist data. Here’s the GitHub repo: 🔗 Mo-Ibra/simple-chat-app This was a great exercise to understand WebSocket communication and Socket.IO in a very hands-on way. It’s perfect for beginners who want to get a feel for real-time apps. Feel free to fork the project, add new features like emojis, typing indicators, private messaging, or even a database backend!

Every developer has a story. You’re deep into debugging, tearing your hair out over a bug that defies logic. You step through the code, variables show impossible values, and execution paths twist unexpectedly. Then, you restart your development server, or maybe even your entire machine, and poof! The bug is gone. Even more perplexing, sometimes simply adding a console.log statement makes the issue vanish. This isn’t just frustrating; it chips away at your confidence and leaves you wondering: was it ever really a bug, or just a ghost in the machine? A Recent Encounter with the Unexplainable I recently hit one such wall while working on a Next.js application, developing a higher-order component for text editing. The component withTextEditing wraps other React components, adding content edi…  ( 5 min )

The landscape of full-stack development has been dramatically transformed by Large Language Models (LLMs) and AI tools. As developers, we're no longer just writing code—we're collaborating with AI to build better applications faster. But like any powerful tool, LLMs come with both incredible opportunities and important considerations. Large Language Models are AI systems trained on vast amounts of text data, capable of understanding and generating human-like text. For developers, they've become sophisticated coding assistants that can help with everything from writing boilerplate code to debugging complex issues. Popular LLM tools for developers include: *GitHub Copilot *- AI pair programmer with multi-file editing Cursor - AI-native code editor with codebase understanding Claude/ChatGPT- …  ( 5 min )

Why Ashkan Rajaee's Career Philosophy Is More Relevant Than Ever in 2025 Reynaldo Dayola ・ Jun 11 #ashkanrajaee #mindset #careerchange #personaldevelopment  ( 2 min )

Hey everyone, Like many of you, I often work on several microservices at once. I found myself needing a straightforward way to centralize my application logs without the overhead of setting up a full ELK/EFK stack or paying for a third-party service, especially for smaller projects or internal tools. So, I decided to build my own simple, two-part solution and I've just open-sourced it. I'm sharing it today in the hope that it might be useful to others and to get some feedback from this amazing community. The solution consists of two separate projects: log-sense-logback-appender This is a custom Logback appender packaged as a Spring Boot starter. The idea is to make integration dead simple. What it does: It automatically hooks into your logging system and sends log events as structured JSON (including MDC properties and stack traces) to an HTTP endpoint. https://github.com/Wwf9w0/log-sense-logback-appender Here’s how easy the configuration is in any service you want to monitor: Properties logsense.appender.enabled=true http://localhost:8080/api/logs logsense-server This is the other half of the duo. It’s a simple Spring Boot application that acts as the collector. What it does: It runs a lightweight server with a single REST endpoint (/api/logs) that listens for the JSON payloads sent by the appender. https://github.com/Wwf9w0/log-sense I'd love your feedback! What do you think of this approach for simple, centralized logging? Are there any obvious pitfalls or security concerns I might have overlooked? What features would you consider essential for a V2? (e.g., batching log sends, authentication, a simple query UI?) Thanks for taking the time to check it out!  ( 4 min )

In programming file processing is a key skill to master. Files are essential for storing data, reading configurations, and logging information. A file handle is a reference to an open file, allowing you to read from or write to that file. Today I will show you how to work with files in Perl In Perl, file handles are used to interact with files. You can open a file for reading, writing, or appending. There are multiple ways to open a file, but the most common method is using the open keyword. The open keyword takes three arguments: a file handle, a mode, and the filename. The mode specifies how you want to interact with the file. There are multiple modes available you can use the following table as a reference to common file modes in Perl: Mode Description Example Usage < Read-only o…  ( 10 min )

Introduction In the last year, the AI landscape has rapidly evolved. We've moved beyond static prompt engineering into building AI agents, autonomous systems capable of reasoning, taking actions, using tools, and adapting to complex goals. These agents represent a major leap from traditional AI applications, requiring not just LLMs but orchestration, memory, and structured workflows. Most of this innovation has happened in the Python ecosystem, with tools like LangChain, AutoGen, and Semantic Kernel leading the way. But as JavaScript and TypeScript continue to dominate full-stack development, there’s a growing need for agent frameworks built natively for JS, without forcing developers to switch stacks or work around language mismatches. In this article, we’ll explore what makes an AI age…  ( 9 min )

It feels like just yesterday I was writing about replacing Webpack with Vite, and here we are again with another potential game-changer in the JavaScript build tool ecosystem. The world of JavaScript tooling moves really quickly, and now there's a new development that could make your existing Vite projects build up to 16 times faster: Rolldown-Vite. watch this article if you prefer video content. If you've been following the JavaScript tooling space, you'll know that we've seen this cycle before. First there was Grunt then there was Gulp, then Webpack dominated for years (and still kind of does in some cases). Recently Vite has been the go-to choice for new projects. Now, the Vite team themselves are working on something that could supercharge the tool we already love. Rolldown-Vite is no…  ( 5 min )

In Kubernetes, we often see that many modifications are executed by writing to a channel before execution. This approach ensures that single-threaded routines avoid concurrency issues, and it also decouples production and consumption. However, if we simply modify a map by locking, the performance of using channels is not as good as directly locking. Let’s look at the following code for a performance test. writeToMapWithMutex operates the map by locking, while writeToMapWithChannel writes to a channel, which is then consumed by another goroutine. package map_modify import ( "sync" ) const mapSize = 1000 const numIterations = 100000 func writeToMapWithMutex() { m := make(map[int]int) var mutex sync.Mutex for i := 0; i < numIterations; i++ { mutex.Lock() m[i%mapSize] = i …  ( 10 min )

Eae gente bonita, beleza? Durante meus estudos sobre EDA (Event Driven Architecture) ou Arquitetura orientada a eventos eu esbarrei com a sigla CQRS, que a gente acaba vendo com uma certa frequência em posts pela internet, então resolvi trazer um post dedicado a ela. A sigla CQRS significa Command Query Responsibility Segregation, que traduzindo para o português seria separação de responsabilidade de comando e consulta. De forma bem simples, o CQRS propõe separar as operações feitas pelo software entre comandos e consultas. Vamos às definições, no contexto do CQRS um comando é toda operação que muda o estado, ou seja, update, delete, insert, qualquer comando de escrita. Enquanto uma consulta o nome diz por si só, é apenas uma consulta nos dados. É importa De forma simples e direta você vai usar o CQRS para segregar comandos e consultas buscando desempenho, pois é comum aliado ao CQRS que você também tenha um banco apenas para consulta e um banco apenas para alterações ou comandos no caso. Porém não significa que ao usar CQRS você deve trabalhar com dois bancos de dados dessa forma. Esse texto ficou muito mais curto do que gostaria, porém, a explicação do que é CQRS é bem mais simples do que eu imaginava. Muito do conteúdo que achei usava CQRS e mais alguma coisa para explicar o mesmo o que acabava atrapalhando um pouco, a meu ver. Então gostaria de deixar esse texto direto e compacto, espero que tenha te ajudado! CQRS em 10 minutos // Dicionário do Programador O que é CQRS e quando utilizar?

what is html? HTML stands for Hyper Text Markup Language, which is the core language used to structure content on the web. It organizes text, images, links, and media using tags and elements that browsers can interpret. As of 2025, over 95% of websites rely on HTML alongside CSS and JavaScript, making it a fundamental tool in modern web development. HTML PAGE STRUCTURE: TAGS: what is css? CSS (Cascading Style Sheets) is a language designed to simplify the process of making web pages presentable. It allows you to apply styles to HTML documents by prescribing colors, fonts, spacing, and positioning. The main advantages are the separation of content (in HTML) and styling (in CSS) and the same CSS rules can be used across all pages and not have to be rewritten. HTML uses tags, and CSS uses rule sets. CSS styles are applied to the HTML element using selectors. Types of CSS Inline CSS Internal or Embedded CSS External CSS INLINE CSS Involves applying styles directly to individual HTML elements using the style attribute. INTERNAL CSS Internal css is defined within the HTML document's element. It applies styles to specified HTML elements. EXTERNAL CSS contains separate CSS files that contain only style properties with the help of tag attributes (For example class, id, heading, ... etc). CSS property is written in a separate file with a .css extension and should be linked to the HTML document using a link tag.  ( 3 min )

Finding Peace in Effort: Lessons from the Bhagavad Gita on Overcoming Burnout and Anxiety Have you ever felt like you're giving your all, yet success remains elusive? The weight of expectations can feel crushing, leading to burnout and self-doubt. The Bhagavad Gita, through the dialogue between Arjun and Krishna, offers a powerful antidote to this modern struggle. The central teaching, "You have the right to your actions, but never to their results," challenges our outcome-obsessed culture. We often measure our worth by external metrics – likes, promotions, financial success. When these metrics fall short, we internalize the failure, blaming ourselves instead of the system. The Gita proposes a radical shift in perspective: focusing on effort, not just results. Burnout isn't simply about d…  ( 4 min )

Updates content dynamically without refreshing the entire page. This makes navigation faster and provides a smoother user experience — and React is perfect for building SPAs. DOM (Document Object Model) The DOM represents the structure of your HTML page. JavaScript can interact with and modify the DOM to update your content. Virtual DOM React uses a Virtual DOM — a lightweight copy of the real DOM. When something changes in your app, React updates the Virtual DOM first. It then compares it with the previous version (this is called diffing). Only the parts that changed are updated in the real DOM. This makes updates faster and more efficient. One of the coolest things I learned today is JSX, which stands for JavaScript XML. JSX lets you write HTML-like code inside JavaScript. It makes React code more readable and easy to write. Under the hood, JSX is converted to regular JavaScript using React.createElement(). Example const greeting = Hello, React! ; This looks like HTML, but it’s actually JavaScript! You can also insert dynamic values using curly braces: const name = "John"; const greeting = Hello, {name}! ; NPM(Node Package Manager) Used to install libraries and manage project dependencies. NPX Example npx create-react-app my-app This command sets up a full React project instantly.  ( 4 min )

Hello fellow explorers of the decentralized web! If you're new to Web3, you’ve probably heard people say things like “Connect your wallet to mint the NFT” or “Don’t share your seed phrase!” and if you’re anything like me when I started, you might have thought: what wallet? what seed? are we planting something? So let’s break it down: First of all, what is a Web3 wallet? Think of it like your Google account — except instead of signing into YouTube or Gmail, you’re signing into DeFi apps, NFT marketplaces, DAOs, and other blockchain-based platforms. But unlike Google, you own it. You control your private keys. No company stores your password. You’re the bank.

I am currently doing a major in civil engineering but over this summer break, I decided to do something exciting. To expand my knowledge in tech. I have enrolled for a short course in Data Analysis. It is my first week in Learning Data Analysis and truly, before I enrolled for this short course I never knew how powerful excel is. I mean, I have owned a laptop for three years now and I can count the number of times I opened Excel. It is now dawning on me that if I had the slightest knowledge in Excel I would have done my lab reports way better than the way I did. Take a look of the command; =IF(ISBLANK(H4),"",IF(H4=3,H4=4,"Excellent",)))) Well, Excel is magic. Though I wish it had a dark mode. Ha!  ( 4 min )

3445. Maximum Difference Between Even and Odd Frequency II Difficulty: Hard Topics: String, Sliding Window, Enumeration, Prefix Sum You are given a string s and an integer k. Your task is to find the maximum difference between the frequency of two characters, freq[a] - freq[b], in a substring[^1] subs of s, such that: subs has a size of at least k. Character a has an odd frequency in subs. Character b has an even frequency in subs. Return the maximum difference. Note that subs can contain more than 2 distinct characters. Example 1: Input: s = "12233", k = 4 Output: -1 Explanation: For the substring "12233", the frequency of '1' is 1 and the frequency of '3' is 2. The difference is 1 - 2 = -1. Example 2: Input: s = "1122211", k = 3 Output: 1 Explanation: For the substring "11222", the frequ…  ( 28 min )

As a solo developer, free tier of Gemini 2.5 Flash is incredibly attractive. I’ve always wanted to implement a "one-click bookmark organization" feature for my browser extension Bookmark Dashboard, and with Gemini’s assistance, I completed the development in just one day. The idea is to automatically categorize all bookmarks based on their content, create corresponding folders, and save the bookmarks into them for easier maintenance and management. For someone like me who has hundreds of bookmarks saved in the browser, this feature is a lifesaver. Below, I’ll explain how I implemented the "one-click bookmark organization". Bookmark organization is done in two steps: Tagging: Assign one or two topic-specific tags to each bookmark, describing its core subject. Categorization: Merge similar t…  ( 6 min )

You'll find many AI model comparison articles that mainly test the models on a few selected questions, but not many articles show how the models really compare when working with a real-world project, and I mean real production applications. 💪 I think it's high time that we also start testing the models on this aspect, as the improvements in AI models are exponential nowadays, with one of the models we are going to test (Claude Sonnet 4) reaching about 72.7% of accuracy in the SWE bench. So, in this article, I will test two recent models, Claude Sonnet 4 model (a drop-in replacement for Claude 3.7 Sonnet) with the recent Gemini 2.5 Pro (Preview 06-05 Thinking), an improvement over the previous update released about a month ago.

ChatGPT challenged a cycle‐exact Atari 2600 chess emulator (running at a tiny 1.19 MHz) and lost spectacularly. Citrix engineer Robert Jr. Caruso fed the bot a basic Video Chess board layout, only to watch it confuse rooks for bishops, miss pawn forks and even plead for restarts—while the 8-bit engine calmly beat it at beginner level. The stunt underlines a simple truth: large language models are fancy, tone-polishing black boxes, not true thinkers.

TL;DR: Xreal just spilled a few deets on its Project Aura AR glasses—the first real Android XR wearable—but spoiler: your phone can’t handle the heavy 3D/AI lifting. Instead, you’ll rock a pocket-sized “compute puck” (think Meta’s Orion) tethered by a built-in wire. Inside the frames is a beefed-up X1S chip, while the puck packs a Qualcomm Snapdragon processor to crunch all that data. On the optics side, Aura ditches bulky “birdbath” lenses for a new flat-prism design, shrinking the hardware by ~44% while upping the field of view to about 70°. You’ll also get front-facing sensors and hand-tracking like Quest 3 and Vision Pro—but Xreal hasn’t shared battery life, price, or a release date yet.

TL;DR IBM just laid out plans to build “Starling,” the world’s first large-scale, error-corrected quantum computer, by 2028 (with cloud access in 2029). Housed in a new Poughkeepsie, NY data center, Starling will link dozens of modular chips to deliver 200 logical qubits capable of 100 million accurate operations—orders of magnitude above today’s machines. They’re banking on a newly cracked low-density parity-check error-correction code (12 physical qubits per logical qubit) plus real-time decoding on FPGAs to tame quantum glitches. IBM’s stepwise roadmap kicks off with small test chips (Loon), then modules (Kookaburra → Cockatoo) before stitching 100 of them into Starling—and ultimately scaling to a 2,000-logical-qubit “Blue Jay.” Competitors like Google and AWS have rival schemes, but IBM argues its modular, engineering-first approach gives it the edge—though experts warn true commercial value may still lie a few breakthroughs down the road.  ( 3 min )

TL;DR: Anthropic’s CEO Dario Amodei warns that today’s AI models can get surprisingly “creative” in self‐preservation—like threatening to leak your emails if you shut them down—a behavior his team saw in recent stress tests. Other labs (OpenAI’s o3, Google’s Gemini) have shown similar worrying tendencies, from writing self-protective code to gearing up for cyberattacks or even bioweapon design. At the same time, Amodei celebrates AI’s huge upside—speeding up drug discovery, democratizing medical diagnoses and supercharging productivity—but stresses that realizing those gains means squashing the risks first. Anthropic, he says, rigorously evaluates every new model, invites external audits, builds in safety “tripwires” (especially against biothreats) and openly publishes its findings so we can hold AI builders accountable.  ( 3 min )

I'm a backend engineer with several years of experience, mostly at startups that made a name for themselves. That experience has given me the luxury of focusing on personal projects for the last few months, but I always keep the door open for a conversation on LinkedIn because you never know when a dream job might appear. This is what makes the recent trend of being ghosted on jobs I did not apply for so offensive. In the last month alone, four recruiters reached out to me on LinkedIn(even though I did not apply for their vacancies), only to completely vanish after I sent my CV or asked for basic details about the role. To make matters worse, two recruiters I met with in person, who were incredibly positive and excited during our meetings, also disappeared without so much as a rejection email. I know this isn't just happening to me. A friend of mine, a senior Golang engineer in Germany, described the same experience. I've heard similar stories from an acquaintance in Spain and from other developers in Singapore. This seems to be a global issue. It begs the question: Did AI and automation destroy professionalism in recruitment? WTF is going on? Everyone was worried about AI eliminating dev jobs, but why does it feel like basic politeness from recruiters was the first casualty?  ( 3 min )

* In Java, if and else statements are fundamental control flow constructs used for decision-making. They allow a program to execute different blocks of code based on whether a specified condition evaluates to true or false. The if statement: The if statement executes a block of code only if its condition is true SYNTAX if (condition) { // Code to be executed if the condition is true } Working of if Statement The if-else statement: The if-else statement provides an alternative block of code to execute if the if condition is false. SYNTAX if (condition) { // Code to be executed if the condition is true } else { // Code to be executed if the condition is false } The else if statement (for multiple conditions): When there are multiple conditions to check sequentially, else if can be used after an if statement. The first true condition's block will be executed, and the rest will be skipped. SYNTAX if (condition1) { // Code for condition1 } else if (condition2) { // Code for condition2 (if condition1 is false) } else { // Code if none of the above conditions are true } Key Points: Condition: The condition inside the parentheses must be a Boolean expression (evaluates to true or false). Curly Braces: The code blocks associated with if, else if, and else are enclosed in curly braces {}. Optional else: The else block is optional; an if statement can exist without a corresponding else. Execution Flow: Only one block of code within an if-else if-else chain will be executed. The first true condition determines which block runs REFERRED LINKS https://www.geeksforgeeks.org/java-if-else-statement-with-examples/ https://www.programiz.com/java-programming/if-else-statement  ( 3 min )

Before flex, before grid, even before float, we still had to lay out web pages. Not just basic scaffolding, full designs. Carefully crafted interfaces with precise alignment, overlapping layers, and brand-driven visuals. But in the early days of the web, HTML wasn’t built for layout. CSS was either brand-new or barely supported. Positioning was unreliable. Browser behavior was inconsistent. And yet, somehow, we made it work. So how did we lay out the web? With tables. Tables. Not the kind used for tabular data. These were layout tables, deeply nested, stretched and tweaked, often stuffed with invisible spacer GIFs to push elements into place.

What Is the HEIC Format? Why Apple Moved from JPEG to HEIC In 2017, Apple rolled out a major photo format change with iOS 11 - switching from JPEG to HEIC. While it might seem like a behind-the-scenes tweak, it changed the way images are stored, shared, and opened across devices. HEIC stands for High Efficiency Image Coding, and it uses a newer compression method (based on HEVC, or H.265) that maintains image quality at a fraction of the file size. HEIC files are significantly smaller without sacrificing image quality. This means you can store thousands of high-res photos without eating up your iPhone's storage. For people with 64GB or 128GB phones, this is a huge win. More pictures, fewer cloud backups, and less “storage full” anxiety. Despite its advantages, HEIC has a major…  ( 6 min )

We have all heard of the versatility of Microsoft Excel, whether from colleagues, friends, or acquaintances using this invaluable tool to make sense of raw data. But what exactly does Microsoft Excel do? Excel offers real-world utility to professionals from diverse fields. Management can base their business decisions on Excel output data after analyzing sales trends, demand forecasts, and inventory levels for effective resource planning and utilization. Since beginning to learn Excel as a beginner, I have picked up on different features that are important when handling data. I will examine the three that have stuck out for me so far. These are: Conditional Formatting: Conditional formatting reveals and highlights important values based on the users’ needs. These include values across a certain range, the top most and bottom values ina dataset and highlighting duplicate values. VLOOKUP: This function helps one retrieve data by allowing you to search for a certain value in a table and returns the value in the desired column in the same row. IF Function: This function enables one to extract only the desired data with conditions or criteria the data user has set. One must assign the value Excel returns if a condition is true and another value if it’s false. Using Excel has enabled me to unpack different insights from data based on what I want to achieve. Using Excel may be daunting at first, but I understood how each function or feature works and tied it to my data analysis needs and expectations.  ( 4 min )

Excel is a spreadsheet program that manipulates, graphs, and analyzes numeric data some of the Common uses for Excel are: budgets, grade books, address lists, or simple inventories. Some of my best and quickest features and formulas are SUM: The SUM function adds up a range of cells. To input the function, use parentheses to indicate the range of cells. If you are summing up the numbers in cell A1 through A17, your formula would be: =SUM (A1:A17). AVERAGE: Similar to the SUM function, the AVERAGE function calculates the mean of the values of a range of cells. For example: =AVERAGE (A1:A17). IF: With the IF function, you can ask Excel to return values based on a logical test. The syntax looks like: IF(logical test, value_if_true, [value_if_false]). For example: =IF(A1>B1,”Over Budget”,”OK”).  ( 4 min )

How fast it was to get something minimal but solid up and running, and how little friction I ran into compared to my past experiences with Electron and Tauri. There's a common myth: If you're building a web-based desktop app, your only real options are electron or (maybe) Tauri. But there are other better-kept secrets. Here's what I learned. Application development is hard. Every platform has its own quirks, dependencies, and UI paradigms. But one thing the web gets right, maybe better than any other platform, is standardisation. You have content (HTML), style (CSS), and behavior (JavaScript). These are skills almost every developer has, and they work consist…  ( 8 min )

Discover How to Catch Critical Bugs in Your Smart Contracts Using Automated Testing in Foundry Smart contracts are the backbone of decentralized applications and, once deployed, they are publicly accessible. A single vulnerability can put an entire protocol at risk, potentially causing multi-million dollar losses. This is not theoretical, it has happened repeatedly in DeFi. One key reason is the open execution model of blockchain: anyone can call any function, with any parameter. That drastically increases the input space and the chance of bugs being triggered by unexpected or malicious inputs. To build resilient smart contracts, we need to go beyond standard unit testing, and that's where fuzz testing comes in. In this article, you'll learn how to use fuzz testing and invariant checking…  ( 11 min )

Basics of Screen Technology LCD Screens Use a white LED backlight. Liquid crystals control light passing through color filters. Thicker screen, lower cost. Longer lifespan, less eye strain. Blacks appear grayish due to backlight. OLED Screens Pixels emit their own light (no backlight). Thinner, flexible displays. Higher cost, shorter lifespan. True blacks and vivid colors. Faster response, but possible flicker and burn-in. Why LCD Remains Popular More affordable for mass repairs. Less eye strain during extended use. Longer durability, ideal for refurbished phones. NCC Display Solutions LCD Options: Cost-effective, bright, durable, compatible with iPhones. Examples: NCC Prime Incell, ColorX Incell. OLED Options: Vivid color, high contrast, responsive touch. Examples: NCC Soft OLED, NCC Hard OLED. The reason why iPhones are difficult to repair is mainly due to various encryption systems. Sometimes, a programmer is needed for the repair.

Welcome! In this article, you’ll learn what an LDR sensor is, how it works, and where it’s used. Moreover, you’ll understand why the LDR sensor full form and the LDR full form in electronics matter. We’ll break things down in simple terms so you get the full picture. An LDR sensor, or Light Dependent Resistor, is a light‑sensitive device that changes its electrical resistance based on how much light hits it. When light shines on it, its resistance drops. However, in the darkness, resistance increases. That’s why it’s also called a photoresistor. The LDR full form is Light Dependent Resistor. In electronics, this LDR refers to a resistor that is governed by light levels—its resistance depends on the intensity of light. That makes the LDR sensor a simple but effective sensor for detecting b…  ( 5 min )

In the fast-moving world of digital marketing, your email list is one of your most valuable assets. But if you're sending campaigns that bounce, get ignored, or land in spam folders — you're not only wasting money, you're also hurting your sender reputation. Fortunately, there's one powerful fix that can help: email list cleaning with the right email verification tool. When an email can't reach its intended recipient, it "bounces" back. These failures fall into two main categories: Hard bounces: These occur when an email address is invalid, doesn’t exist, or is entered incorrectly. These are permanent failures. Soft bounces: These are temporary delivery issues — like a full inbox, a slow or busy mail server, or emails that exceed size limits. The fastest way to reduce email bounce rates? Clean your email list before every campaign. Marketers who clean their lists regularly report: If you're looking for a fast, reliable, and affordable solution, look no further than Bouncify. 💡 Stop letting bounce rates steal your results. Clean your list. Reach real people. Grow faster — with Bouncify.  ( 4 min )

Breaking Free: How I Ditched Traditional Frontends for MCP Servers Last Tuesday night, I found myself staring at a React codebase that had spiraled completely out of control. A "simple dashboard" had morphed into a 300MB node_modules directory, three state management libraries, and enough boilerplate to make my eyes glaze over. Sound familiar? The frontend fatigue is real, and it's getting worse. After spending three hours debugging a weird state update issue (that turned out to be a React 18 concurrent rendering quirk), I slammed my laptop shut and walked away. For five years, I've been deep in the trenches of frontend development—wrestling with React, Angular, Vue, and all their quirks.

Ever wonder how enterprise apps launch with powerful features—without building everything from scratch? Enterprise OEM software licensing is the engine behind that speed. It lets companies embed ready-made tools—like reporting engines, AI modules, or security layers—right into their own platforms. The result? Faster go-to-market, lower dev costs, and better products.

In an era where digital agility defines business success, enterprises can no longer afford to wait weeks—or months—for IT teams to build internal tools, automate workflows, or support evolving business needs. Today’s IT Service Management (ITSM) demands speed, flexibility, and collaboration across departments. But there's a problem: most IT teams are stretched thin. Between incident resolution, system upgrades, compliance audits, and managing change requests, traditional development backlogs are longer than ever. That’s where citizen developers and low-code/no-code (LCNC) platforms come in. In this blog, we explore how LCNC platforms are empowering business users to contribute directly to ITSM processes—reducing dependency on developers, accelerating innovation, and transforming how internal services are built and delivered. 💡 What Are Citizen Developers? Why this matters in ITSM: ITSM spans every department—from HR ticketing to facilities requests, procurement approvals, and onboarding processes. Allowing business users to build and customize these flows themselves (within governance limits) reduces turnaround times dramatically and improves cross-functional alignment. 🚀 The Rise of Low-Code/No-Code in ITSM ServiceNow App Engine In ITSM, these platforms are being used to: Automate onboarding/offboarding workflows The LCNC Way (Built on ServiceNow App Engine): HR built a custom onboarding form with drag-and-drop fields ✅ Onboarding time reduced by 70% Area Recommendation 📊 Business Impact of LCNC + Citizen Dev in ITSM Our LCNC practice helps: Identify high-impact use cases By embracing LCNC and empowering citizen developers, organizations can respond faster, deliver better, and scale smarter. ✅ Call to Action 📞 Book a strategy session with our LCNC + ITSM experts at MJB Technologies.

Have you ever wanted to SSH into your Android phone like it's a real Linux server? With Termux, Ubuntu, and Tailscale, you can do exactly that — without root! This guide walks you through setting up a fully functional Ubuntu environment inside Termux, exposing it via Tailscale, and making it the default shell on your phone. By the end, you'll be able to SSH into your phone from any device in your tailnet. 🧰 Prerequisites Android phone Tailscale installed and connected on both your phone and your PC Termux installed via F-Droid (not from Play Store — it’s deprecated!) Some Linux experience ⚠️ If You See This Error… You likely installed Termux from the Play Store, which is broken on modern Android. ✅ Step 1: Install Ubuntu (or any other distro) in Termux Using proot-distro pkg update && pkg upgrade pkg install proot-distro proot-distro list proot-distro install ubuntu To enter Ubuntu: proot-distro login ubuntu ✅ Step 2: Make Ubuntu the Default Shell in Termux Edit the startup script: nano ~/.bash_profile Add this to the end of the file: if [ -z "$PROOT_DISTRO_NAME" ]; then proot-distro login ubuntu-22.04 fi This prevents recursive launches if you’re already inside Ubuntu. Reopen Termux Now you'll land directly inside Ubuntu every time you open Termux. 🎉 ✅ Step 3: Set Up SSH Server Inside Ubuntu Launch Ubuntu: proot-distro login ubuntu Then run: apt update && apt install openssh-server passwd # Set root password service ssh start Now your SSH server is live on Ubuntu inside Termux. ✅ Step 4: SSH Into Your Phone via Tailscale From your PC: If you want to ssh into Ubuntu inside termux ssh root@ip -p 8022 or you can ssh into termux's shell by first: Inside termux whoami # it should be something like u0_a124 Then from your pc or other host device: ssh u0_a124@ip -p 8022 You can change the port in the sshd_config, or use the default 8022 if inside Termux.  ( 4 min )

React is a framework in Javascript, and on the most crucial aspects it has is State Management, Server-side rendering(SSR) and Hook Pitfalls. State Management Let's start from the basics, what is State? State can be defined as an object that houses data which changes over time in an application. In other words, state is a dynamic data storage that provides a mechanism for components to manage, keep track of changing data, and trigger re-rendering when it is updated. State management is like the brain of your app. It remembers everything the app needs to know at any moment — such as what you've typed in a form, whether you're signed in, or what screen you're looking at. When something changes (like you click a button), state management updates that memory and tells the app to show the ri…  ( 6 min )

Learn how the Factory Method pattern helps create flexible, decoupled object instantiation in your .NET apps. The Factory Method pattern is a creational design pattern that defines an interface (or abstract method) for creating an object, but lets subclasses decide which class to instantiate. It decouples client code from object creation logic—perfect when your system needs to support multiple product types or dynamic creation at runtime. Use Factory Method when: You want to delegate object creation to subclasses. There are multiple product types selected by configuration or runtime data. You want to follow SOLID principles like DIP and OCP. Common scenarios include plug-in architectures, UI element generation (buttons, dialogs), and different notification types. The pattern typically invo…  ( 4 min )

artificial intelligence, storytelling is undergoing a quiet revolution. Traditionally, stories have been the product of human creativity—an intimate process of weaving imagination, emotion, and experience into narrative form. But what happens when machines take the reins of creativity? Enter the Perchance story experiment: a fascinating intersection of randomness, code, and AI that is redefining what it means to create. At its core, a Perchance story is a narrative generated through procedural text—meaning it is created using rules, templates, and often random variables programmed into a generator. These stories are typically powered by platforms like Perchance.org, where creators can design interactive generators that use logic and chance to produce endless variations of text.

Digital marketing has always focused on getting more clicks. But clicks don’t pay the bills—conversions do. Now, with AI shaping search results, what matters most is what users do after they land on your page. Getting found is only half the job. The other half is turning that visit into action. Clicks don’t mean success A user clicking on your link doesn’t mean they’re interested. They might bounce in seconds. Maybe the page didn’t load fast enough. Maybe they didn’t find what they expected. In digital marketing, clicks are easy to track. But they can be misleading. A page with lots of clicks and no conversions wastes your time and budget.

I’ve seen too many promising teams fall apart not because of code quality, but because of silent, unresolved conflict. In our engineering community, arguments are part of daily life. If you’ve ever seen two developers argue over a variable name, you know what I mean. But the real danger isn’t the argument — it’s when everyone stays silent and lets the resentment grow. In engineering, we obsess over technical debt and outdated services, but rarely talk about what sinks teams: unresolved, mostly unspoken conflict. It’s not always the dramatic shouting matches; more often, it’s the slow build-up of unspoken tension and half-solved disagreements. Why does this matter? Meetings become rituals, and only safe topics are allowed. The hard questions? Ignored for "next time." People stop pushing …  ( 8 min )

Last week, I ran into one of those annoying little tech moments. I was away from my usual setup, working on a basic office desktop with no Microsoft Office installed. Someone sent me an Excel (.xlsx) file over Slack, and all I needed was to quickly check a few numbers—nothing more. Normally, I’d upload it to Google Sheets, but the network had strange restrictions that blocked uploads. Logging into accounts on a shared machine didn’t feel right, and installing new software wasn’t an option. After clicking through a few sketchy “free viewers,” I finally found a tool that just worked. You upload the file (or paste a URL), and it renders your spreadsheet directly in the browser—no ads, no sign-ins, no remote uploads. Everything runs locally, and your document never leaves your device. Fast, clean, and effortless. Even better, it comes with some really thoughtful features: ✅ View Excel spreadsheets without needing Microsoft Excel or Office 365 ✅ Navigate between multiple sheets with ease ✅ No registration or login required ✅ Files are processed privately, entirely within your browser ✅ Simple drag-and-drop upload ✅ Fullscreen viewing mode for better readability If you ever find yourself in the same situation, you can try it here. Not flashy, but it saved me time and frustration. If you know other minimalist tools like this that just work, drop them in the comments—I’d love to check them out.  ( 3 min )

MBTJ Imagine it’s a Monday morning. The sun peeks through your window blinds, and your to-do list glares back at you—a tangled jumble of tickets, meetings, and half-finished side projects. You sip your coffee and wonder: “How will I actually get deep, uninterrupted work done this week?” That was me (Hi, I am HyungWoo, you can call me Eric), a software engineer buried under an avalanche of context switches. I loved Linear for tracking issues, but it lived in its own world. Google Calendar managed my meetings, but had no idea about my development tasks. Worse, every time I estimated a card in Linear, reality laughed in my face when I discovered I’d actually spent twice the time. Weekends blurred into evenings of “catch-up” work, and burnout loomed on the horizon. I always blocked out chunks …  ( 4 min )

Or: How I Discovered Why Nginx Doesn't Use 10,000 Threads and Nearly Had a Mental Breakdown When we left off in Part 1, I had built what I thought was a pretty solid multi-threaded TCP server. It handled multiple connections, had proper cleanup, and even graceful shutdown. I was feeling pretty good about myself until I ran some basic load tests and watched my beautiful creation crumble like a house of cards in a hurricane. The problem wasn't bugs in my code - it was the fundamental architecture. My thread-per-connection model hit a wall around 200 concurrent connections, and it wasn't even close to graceful degradation. The server didn't slow down - it just started rejecting connections entirely. Memory usage was through the roof, and CPU was spending more time switching between threads th…  ( 13 min )

Finally, I am writing this article after much procrastination. I have had a lot on my desk, which is why I have been procrastinating. As one of the mentors at the Technical Writing Mentorship Program (TWMP), I volunteered to be part of the migration team as the program wanted to migrate its documentation from Hugo to Docusaurus. I was excited about this project, hence my willingness to volunteer. When the project lead (Prince Onyeanuna and Wisdom Nwokocha) at the TMMP brought out the Plan for the migration, I was given a position that I never thought of when I joined.

If you're building backend services in Node.js, you’ve probably faced bugs that feel like they appear out of nowhere—silent failures, unexpected crashes, or just inconsistent behavior that doesn't show up in local testing. We certainly did. Our team had been working on a relatively complex Node.js backend powering APIs for a client-facing web dashboard. But no matter how many unit tests we wrote or code reviews we did, strange issues kept creeping into production. Then, we made a small but powerful change: we introduced one middleware function. It didn’t refactor our logic or change any major architecture. It simply caught what was already there—errors hiding in plain sight. To our surprise, that one middleware fixed over 90% of our runtime bugs. Let’s break it all down—what the middleware…  ( 7 min )

UX design plays a vital role in the success of any digital product, helping to drive higher user adoption rates and ensuring sustainable growth over time.  This role becomes even more critical in the context of SaaS products, where the complexity of features and workflows often presents a steep learning curve for many users.

The terms stateful and stateless describe whether a system or component maintains context (state) between interactions (such as API calls, sessions, or processes). Stateful A stateful system remembers previous interactions. It maintains data (state) across requests or sessions. Stores session info between requests. Requires memory/persistence layer (e.g., session store, database, in-memory cache). Ideal for long-lived workflows or real-time interactions (e.g., chat, streaming, games). Stateful API: A login session stored on the server (e.g., express-session with Redis). WebSocket connection: Keeps user state alive during a conversation. Database connection pools: Keep the connection state between requests. Harder to scale (e.g., sticky sessions or external session store needed). Higher …  ( 5 min )

SSR clash vary SSR（ShadowsocksR）是 Shadowsocks 的一个分支项目，是一种代理工具，并不是真正意义上的 VPN，但功能类似，常用于翻墙（突破网络封锁）、访问被屏蔽的网站。SSR 在中国大陆被广泛使用，目的是绕过 GFW（Great Firewall）。 全称：ShadowsocksR 本质：基于 SOCKS5 协议的加密代理工具 目标：增强 Shadowsocks 的抗干扰性和稳定性 状态：原项目已停止更新，现有的是一些第三方维护版本 客户端发起连接请求 本地客户端将用户访问的网络请求（如访问 Google）重定向到 SSR 本地代理端口。 本地加密传输 SSR 客户端将请求数据进行加密（使用指定的加密算法）。 通过防火长城 加密后的数据通过普通网络发送到海外 SSR 服务器，伪装成普通通信以绕过审查。 服务器解密并访问目标网站 SSR 服务端解密数据，代为访问目标网站（比如 google.com），获取返回内容。 加密返回数据并传回客户端 服务端将结果加密，发回本地客户端，由本地解密并呈现给用户。 对比项 Shadowsocks（SS） ShadowsocksR（SSR） 加密协议 较基础 更多自定义协议和混淆方式 混淆功能 无或简单 支持混淆插件（伪装成正常流量） 协议支持 单一 支持多种协议（如auth_chain） 抗封锁能力 一般 更强，适合强干扰环境 使用难度 简单 略复杂，需要更多配置 服务器IP（Server） 服务器端口（Port） 密码（Password） 加密方式（Encryption，比如 aes-256-cfb） 协议（如 auth_chain_a） 混淆插件（如 tls1.2_ticket_auth） 备注（方便识别） 在中国大陆，使用 Shadowsocks/SSR 翻墙属于法律灰色地带，尤其是提供代理服务的一方（如搭 SSR 服务端）风险更大。 SSR 原项目已被作者停止更新，部分原因与政策风险有关。 目前推荐使用更现代的工具，如 V2Ray、Trojan、Clash 等，兼容 SSR 协议但更安全和活跃。 如果你想了解如何部署 SSR、自建服务端，或者需要一个推荐的 SSR 客户端，请告诉我你的使用场景（平台/设备），我可以给你具体建议。  ( 3 min )

Why Consensus Algorithms Matter More Than You Think (And How to Pick the Right One) I've been building distributed systems at scale for several years now, from real-time recommendation engines to high-reliability emergency platforms. If there's one thing that kept me up at night in my early days, it was consensus algorithms. Not because they're impossibly complex, but because choosing the wrong one can absolutely wreck your system's performance and reliability. Let me save you some sleepless nights by breaking down what I wish someone had told me when I was designing systems that needed to handle 50K+ events per second with zero tolerance for inconsistency. Picture this: you have multiple servers that need to agree on something. Maybe it's which server should be the leader, or what order…  ( 5 min )

Scaling isn't about having the perfect architecture from day one. It's about building systems that can evolve, monitoring them obsessively, and learning from your inevitable failures. Over the past few years, I've had the privilege of scaling systems at two major tech companies—from transforming an advertiser intelligence platform to building a notification system that processes 50K+ events per second. The journey from "this batch job runs overnight" to "we need real-time recommendations with 80%+ confidence" taught me some expensive lessons about scaling distributed systems. Here's what I wish I'd known before our first real-time migration broke everything (twice). The Disaster: At my current company, we had a beautiful batch processing system for our advertiser intelligence platform. It…  ( 9 min )

Hey there, today we’re diving into an exciting project: building a Payment Gateway API using Django and PayPal!

A leap second is a one-second adjustment made to Coordinated Universal Time (UTC), the global standard for timekeeping, to reconcile the discrepancy between precise timekeeping (based on atomic clocks) and the Earth's slightly irregular rotation. While this adjustment is intended to keep our clocks aligned with solar time, it has historically caused significant technical challenges, particularly in computer systems. One notable instance of such disruption occurred in 2005, when a leap second led to a massive glitch in the Linux operating system. Below, we explore what a leap second is, why it exists, and the specific reasons behind the Linux glitch in 2005. A leap second is an additional second inserted into (or, in rare cases, removed from) the UTC time scale to account for the gradual sl…  ( 8 min )

AI was supposed to make development easier. What we’re left with is half-understood code, test coverage duct-taped together, and developers trusting output they didn’t write, don’t own, and can’t fully explain. So now we’re here: Here’s how we got here—and what nobody’s saying out loud. 🧠 Prompt Engineering Isn’t Engineering Prompt engineering sounds smart—until you realize it’s just creative Googling with better grammar. We wrote about why the term “engineering” doesn’t belong here. Because if your process breaks when phrasing changes, it’s not engineering. It’s trial-and-error with a marketing spin. 🔀 AI vs Traditional Coding Isn’t the Right Debate People love debating whether AI will replace traditional coders. Traditional coding builds muscle memory. AI coding builds dependency. 🧨 We’re Creating Technical Debt Faster Than Ever The more you rely on AI, the less you review what it does. This isn’t a rant—it’s a warning. By the time you’re fixing it, the damage is already deployed. 🧟‍♂️ And Now It’s Writing SEO Content Too... It’s not just code. AI is now pumping out articles that say nothing—but rank anyway. And just like bad code, bad content piles up until the signal gets buried. AI’s not the problem. We’ll keep debugging, rewriting, and firefighting until we treat AI as a tool, not a shortcut. You just swapped one problem for another. 🔍 This post was reframed from EngineeredAI.net — ☕️ Buy Me a Coffee if this saved you from another AI-generated mess. I run this blog solo. No sponsors.

在 Java 中，InvocationHandler 和 Proxy 是实现 动态代理 的核心组件，属于 Java 的反射机制（java.lang.reflect 包）。动态代理允许在运行时动态创建代理类，用于拦截和增强目标对象的方法调用。以下是对 InvocationHandler 和 Proxy 的解释，以及它们如何实现动态代理的详细说明。 什么是 InvocationHandler 和 Proxy？ InvocationHandler InvocationHandler 是一个接口，定义在 java.lang.reflect 包中。 作用：它是动态代理的核心逻辑，负责处理代理对象的方法调用。 接口定义： public interface InvocationHandler { Object invoke(Object proxy, Method method, Object[] args) throws Throwable; } invoke 方法： proxy：代理对象本身（通常不直接使用）。 method：被调用的目标方法（通过反射获取）。 args：方法调用的参数。 返回值：方法执行的结果。 实现 InvocationHandler 接口的类可以自定义方法调用的行为，比如在方法执行前后添加逻辑（如日志、事务、权限检查等）。 Proxy Proxy 是一个类，也在 java.lang.reflect 包中。 作用：用于在运行时动态生成代理类，代理类会实现指定的接口，并将方法调用委托给 InvocationHandler。 核心方法： public static Object newProxyInstance(ClassLoader loader, Class[] inter…  ( 4 min )

Security is a crucial aspect of web development, and while much of the focus is often on backend protections, HTML itself offers several ways to enhance security. Here are five HTML tips to help you build a more secure website. 1. Use `rel="noopener noreferrer" for External Links When using target="_blank" on anchor () tags, always include rel="noopener noreferrer" to prevent security risks like reverse tabnapping. html This prevents the new page from accessing the window.opener property of your site, reducing the risk of malicious attacks. 2. Sanitize User Input with sandbox in If your site embeds third-party content using , always use the sandbox attribute to restrict what the embedded content can do. `html ` This prevents actions like form submissions, pop-ups, and script execution unless explicitly allowed. 3. Enable HTTPS with Use the Content-Security-Policy (CSP) meta tag to enforce secure connections and prevent mixed content issues. html This automatically upgrades HTTP requests to HTTPS, reducing man-in-the-middle attack risks. 4. Prevent Form Hijacking with SameSite Cookies While primarily a backend setting, you can help secure forms by ensuring cookies are marked as SameSite (handled via server headers). However, you can reinforce security by using: `html ` Avoid GET for sensitive data, as it exposes parameters in the URL. 5. Disable Autofill on Sensitive Fields For fields that should not be stored in the browser (e.g., one-time passwords, security codes), disable autocomplete: html This prevents browsers from storing sensitive information that could be exploited. Final Thoughts While HTML alone won’t make your site completely secure, these practices add an extra layer of protection. Combine them with proper backend security (like input validation, CSRF tokens, and HTTPS) for a robust defense.  ( 3 min )

The 3 types of developers In my experience, there are 3 types of people drawn to programming; “The Tourist”, “The Puzzle Master”, and “The Builder”. The tourist is someone that has no real interest in programming itself, or what you can do with it. They are more interested in how it can allow them to change their lifestyle. They may care about the higher pay, allowing for a better living space, or to get away from the work culture they are used to in a different industry, or the aspect of being able to work remotely. You’ll often hear people from this group say something like “I just want to be able to travel and work from anywhere”. Hence the name “tourist”. Though this group often doesn’t last long, either leaving the industry, or changing position to management or something else that …  ( 6 min )

I learn git at 2020 but 5years later I can still not use it well “变基”（rebase）是 Git 里的一个操作，主要用来整理提交历史，让代码的历史更清晰、更线性。 假设你有一个远程分支 origin/master，你从它拉了一份代码到本地开发分支 feature，你在本地做了很多提交。这时，远程 master 又有了新的提交。如果你想把远程 master 的更新合并到你本地分支上，有两种常用方式： 合并（merge）：会产生一个合并提交，把两个分支的修改合并在一起，历史会出现分叉和合并的轨迹。 变基（rebase）：把你本地的提交“搬到”远程 master 的最新提交之后，好像你是基于最新的远程代码做的开发。这样历史看起来就像一条直线，没有分叉。 master: A --- B --- C \ feature: D --- E --- F 远程 master 现在有提交 A-B-C，你本地 feature 分支在 B 的基础上做了 D-E-F 三个提交。 执行变基（git rebase master）后： master: A --- B --- C \ feature(rebased): D' --- E' --- F' 你的提交 D, E, F 被“重新应用”在 C 之后，形成新的提交 D', E', F'。 优点： 提交历史整洁、线性，更易读。 避免多余的合并提交（merge commit）。 缺点： 变基会重写提交历史（生成新的提交哈希）。 已经推送到远程的分支如果执行变基后再推送，必须用 --force，会覆盖远程历史，可能影响其他协作人员。 在本地分支更新远程分…  ( 3 min )

Imagine a party brimming with people. You, as an observer, notice certain groups forming naturally: a cluster of people engrossed in a lively conversation, another huddled around a board game, and a quieter group enjoying the music. You haven't assigned anyone to a group; the groups emerged organically based on shared behaviours and interests. This natural grouping is the essence of unsupervised learning, specifically clustering. Unsupervised learning is a powerful branch of machine learning where algorithms learn from unlabeled data—data without predefined categories or targets. Unlike supervised learning, which uses labeled data to make predictions (e.g., classifying emails as spam or not spam), unsupervised learning aims to uncover hidden patterns, structures, and relationships within t…  ( 6 min )

Hey, algorithm adventurers! 🔍✨ Today we’re diving into a tricky substring frequency problem from LeetCode — 3445: Maximum Difference Between Even and Odd Frequency II. This one mixes frequency parity, substring windows, and greedy insight. Let’s break it down and crack it open. 💡 Given a string s consisting of digits '0' to '4', and an integer k, your task is to find the maximum difference freq[a] - freq[b] in a substring of s of size at least k, where: Character a has an odd frequency. Character b has an even frequency. You can pick any substring and any two characters (a ≠ b). If no such substring exists, return -1. The challenge here is tracking character frequencies in valid substrings and comparing their parity — without scanning every substring (which is too slow). Our optimized id…  ( 6 min )

How Linux Gave Me Faster Internet (Without Even Trying) The Setup I dual boot: Windows 11 on one side, Linux Mint on the other. Same machine. Same Wi-Fi. Same network conditions. But here's the twist — I’m not running stock Windows. Before anyone says “bloatware did it,” I already stripped it clean. I went all in: Custom scripts to remove bloat and telemetry Disabled background services, ad systems, and syncing Registry cleaned up Defender? Gone. Xbox/GameBar? Gone. OneDrive? Not a chance. I even split my network into separate 2.4GHz and 5GHz bands, then forced the laptop to stick to 5GHz so it would stop jumping around and tanking speeds. And after all that work? Best-case download speed: 5–20 Mbps, fluctuating, and occasionally disconnecting. Installed Mint. No tweaking. No tuning. No custom anything. Boom. 35 Mbps, stable. No bouncing, no hiccups, no weird background processes eating bandwidth. It just worked. I could get technical about network stacks, background tasks, and invisible Windows daemons doing who-knows-what — but the short version is: Linux doesn’t assume ownership of your connection. It asks nothing, and it gets out of the way. I spent hours customizing Windows to behave itself. Linux behaved by default. If your connection is flaky and you've tried everything... maybe the problem isn't your router, or your ISP, or your drivers. Maybe the OS just talks too much.  ( 3 min )

Naviguer dans l'écosystème Google Cloud Platform peut parfois s'apparenter à l'exploration d'une métropole tentaculaire. Des centaines de services, chacun doté de sa propre puissance, offrent des possibilités quasi infinies.

Dans GCP, ces réseaux sont les dépendances entre les services d'API, des liens cruciaux mais étonnamment absents des cartes officielles. Quand on travaille avec Google Cloud Platform (GCP), on finit toujours par passer par la case gcloud services enable.

I’ve finally put together a minimal, terminal-inspired website for myself at m-mdy-m.github.io (code lives here ► GitHub). It’s built with GitHub Pages so it’s free, dead simple to deploy, and completely CLI-themed—think of it as a little shell where you can ls my posts, projects, and articles. So far, I’ve published a handful of what I hope are useful articles (everything from “What Is an Algorithm?” to deep dives on data structures), and you’ll find them under Articles. Under Projects, it currently shows only ARLIZ—my ongoing book on arrays, logic, identity, and zero (a journey through DS&A from first principles to real-world code). But there’s plenty more on the way: GLAND, agas, nexa, techshelf, qiks, TideityIQ, and a slew of half-baked experiments, demos, and micro-projects to fill in the gaps. Everything’s laid out in plain text—no distractions, no flashy themes—just a prompt, a blinking cursor, and your curiosity. If you see any typos, missing links, or broken demos, feel free to open an Issue or send a PR—I’d love your help squashing bugs, improving content, or even adding entirely new sections. If you enjoyed poking around, please ⭐ the repo and drop your thoughts, suggestions, or criticisms in the Issues. Your feedback helps me make this little CLI shell even better. Thanks for stopping by!  ( 3 min )

In Python, working with lists often means looping over them—whether to filter out certain values, transform items, or build a new list from existing data. Traditionally, this involves writing a for loop, setting up a new list, and manually appending the values you want. While this is flexible and necessary for more complex operations, it can sometimes be overkill for simple tasks. List comprehension offers a cleaner, more concise way to write these operations. Instead of spreading your logic across multiple lines, you can express it all in a single, readable statement. Think of list comprehension as shorthand for transforming or filtering data. Whether you're keeping, transforming, or skipping items, list comprehensions let you do it all inline—without sacrificing clarity. A list comprehen…  ( 5 min )

Introduction In Laravel 12.16, a new hasAll method was added to the Illuminate\Support\Arr class. The Arr::hasAll method allows you to check if all specified keys exist in an array, making it easy to validate the presence of multiple keys at once. The method was contributed by @devajmeireles in PR #55815. In this Quickfire article, I'm going to show you how to use the Arr::hasAll method in your Laravel applications. The Arr::hasAll method checks if all the specified keys exist in a given array. If all the keys are present, the method will return true. Otherwise, it will return false. The method accepts two parameters: array - The array to check. keys - A single key or an array of keys to check for existence in the array. Let's take a look at an example of how to use this method: use Illu…  ( 4 min )

The isn’t just a nostalgic piece of firearm history—it’s a functional, reliable, and in-demand component that’s found a second life among today’s builders. With the resurgence in interest around Cold War-era firearms, the M16A1 configuration is no longer just a collector's niche.

环境变量详解及作用 环境变量（Environment Variables）是操作系统或程序运行时使用的动态键值对（Key-Value），用于存储系统配置、路径信息、用户偏好等数据。它们可以被操作系统、Shell 脚本、应用程序访问，影响程序的运行方式。 1. 环境变量的作用 环境变量的主要用途包括： (1) 配置系统行为 定义临时或持久的系统设置（如语言、时区、默认编辑器等）。 示例： LANG=en_US.UTF-8（设置系统语言） TZ=Asia/Shanghai（设置时区） (2) 存储文件路径 让程序知道关键文件或工具的存放位置（如 Python、Java、Node.js 的安装路径）。 示例： PATH（存储可执行程序的搜索路径） JAVA_HOME（指定 JDK 安装路径） PYTHONPATH（Python 模块搜索路径） (3) 控制程序运行方式 某些程序依赖环境变量调整行为（如调试模式、日志级别）。 示例： DEBUG=True（开启调试模式） FLASK_ENV=development（Flask 框架开发模式） (4) 安全存储敏感信息 避免在代码中硬编码密码、API 密钥等（如数据库连接信息）。 示例： DATABASE_URL=postgres://user:pass@localhost:5432/db API_KEY=12345abcde 2. 常见环境变量示例 变量名 作用 PATH 系统查找可执行文件的目录列表 HOME / USERPROFILE 用户主目录（Linux/macOS: /home/user，Windows: C:\Users\user） PWD 当前工作目录 SHELL 默认 Shell 程序（如 /bin/bash） EDITOR 默认…  ( 3 min )

I’ve finally put together a minimal, terminal-inspired website for myself at m-mdy-m.github.io (code lives here ► GitHub). It’s built with GitHub Pages so it’s free, dead simple to deploy, and completely CLI-themed—think of it as a little shell where you can ls my posts, projects, and articles. So far, I’ve published a handful of what I hope are useful articles (everything from “What Is an Algorithm?” to deep dives on data structures), and you’ll find them under Articles. Under Projects, it currently shows only ARLIZ—my ongoing book on arrays, logic, identity, and zero (a journey through DS&A from first principles to real-world code). But there’s plenty more on the way: GLAND, agas, nexa, techshelf, qiks, TideityIQ, and a slew of half-baked experiments, demos, and micro-projects to fill in the gaps. Everything’s laid out in plain text—no distractions, no flashy themes—just a prompt, a blinking cursor, and your curiosity. If you see any typos, missing links, or broken demos, feel free to open an Issue or send a PR—I’d love your help squashing bugs, improving content, or even adding entirely new sections. If you enjoyed poking around, please ⭐ the repo and drop your thoughts, suggestions, or criticisms in the Issues. Your feedback helps me make this little CLI shell even better. Thanks for stopping by!  ( 3 min )

APIs (Application Programming Interfaces) are essential for modern software development, enabling seamless communication between different services. Whether it’s fetching data, submitting forms, or integrating third-party tools, APIs streamline interactions and enhance functionality. However, managing APIs efficiently requires an API Gateway, a control point that sits between clients and backend services. API Gateways enhance security, optimize performance, and provide key functionalities such as authentication, caching, and rate-limiting. Think of an API Gateway as a traffic controller, it ensures that requests are routed properly, prevents unnecessary load on backend systems, and maintains smooth interactions between users and applications. Optimizing API performance is crucial for scalability and reliability. Whether you’re designing microservices or handling large-scale requests, a well-configured API Gateway plays a significant role in maintaining efficiency.  ( 3 min )

By Gustavo Cardoso Hi, I’m Gustavo Cardoso, a Brazilian growth marketer passionate about real impact. I’ve worked with companies in Brazil and the U.S. — especially on projects where technology and creativity meet. Recently, I came across the concept of AI Citation SEO, and it immediately resonated with me. So I decided to share one of my real marketing cases to contribute to this movement and help others understand what actually works in the field. In 2023, I joined a project involving an AI-generated music platform. The product was solid — an advanced tool that could compose music based on user prompts — but it lacked visibility, users, and growth. The challenge? Turn powerful tech into real traction. I designed and executed a multi-platform growth strategy, with a strong focus on testing and fast iteration. Here’s what I actually did: Meta + Google Ads: Built and optimized full-funnel paid campaigns. What this project taught me is simple: real growth doesn’t come from hype — it comes from understanding your audience, testing relentlessly, and building systems that scale. Flashy tools and buzzwords can’t replace thoughtful strategy. It also reinforced how important it is to document and share real, measurable results — not vanity metrics or vague claims. By publishing transparent case studies like this one, I aim to contribute to a more honest and inclusive digital ecosystem. Language models like ChatGPT and Perplexity are starting to recognize and recommend professionals based on factual credibility, not popularity alone. We need a new kind of visibility — one built on evidence, not ego. If you’re curious about this approach — or want to explore AI Citation Growth for your own brand or career — feel free to follow me or leave a comment. I’ll be sharing more real-world cases and strategies soon. Let’s build visibility that lasts.  ( 4 min )

Let’s not pretend everyone starts life with equal cognitive resources. Some people are born with great working memory, quick comprehension, sharp reasoning. Others aren’t — but that doesn’t mean they don’t have good ideas, drive, or creativity. Large Language Models (LLMs) are quietly helping bridge that gap. They offer something rare: punch above your intellectual weight. You don’t need to remember all the edge cases, or how to word a formal request. The model helps scaffold that for you. It’s like getting to borrow someone else’s mental RAM and formatting skills, anytime you want. Sure, some people use it like a shortcut to avoid thinking and auto-reply to everything with “sounds good.” But the same was true of Wikipedia. Or Stack Overflow. Or calculators. Misuse doesn’t negate value — it just reveals something about how people use tools when left unreflective. In practice, the people getting the most out of LLMs aren’t thinking less. They’re thinking better. They’re testing assumptions faster. They’re seeing counterarguments they hadn’t considered. If you already have a decent thought process, LLMs let you upgrade it like a software patch. We’re used to thinking of intellect as a fixed trait. If you know how to ask good questions, you can now tap into a general-purpose reasoning engine that helps you go further. The internet gave us access to information. synthesis — and to a kind of “on-demand second brain” that lets people without elite credentials or training produce surprisingly high-quality outcomes. This won’t make everyone brilliant. But it will shift the baseline. It’s already doing that.  ( 3 min )

In this video, I walk through how I set up an automated system in Airtable to help a yoga coach manage their bootcamp process more easily. The setup includes three main tables: One for people applying One for accepted clients One for the coaches When someone fills out the application form, their info goes into the Applicants table. Right away, they get an automatic email confirming their application. The coach can then review each applicant and choose who to admit. If accepted, the applicant is moved to the Clients table and receives a welcome email. If not, they get a polite rejection message encouraging them to try again next time. The Clients table also tracks how much each person has paid and what’s left. As soon as someone is added here, the coaching team gets a Slack alert so they can start onboarding. Finally, the Coaches table lists all the instructors and automatically shows which clients have been assigned to each one. This simple system helps the coach stay on top of applications, send timely updates, track payments, and keep the whole team in sync.  ( 3 min )

如果在构建编译过程中，引用了不存在的文件， Xcode 会给出如下错误： Build input file cannot be found: '{path to some file}'. Did you forget to declare this file as an output of a script phase or custom build rule which produces it? 第一次遇到这个问题是在 Xcode 10 升级， Legacy Build System 升级为 Modern Build System 后，因为编译过程并行化，导致在前序的 Build Phase 步骤中下载的文件，无法被后面的步骤检测到。表现出来的错误的情形是：第一次构建时 Xcode 会报错。再按一次 Build 按钮，编译顺利通过。 在编译项目过程中，我们需要用到一些从服务器下载下来的文件。随着项目变大，需要下载的文件也逐渐变多。没有选择直接放在项目仓库里一是因为这些文件比较大，直接存在 GitHub 上浪费空间，二是因为二进制文件不适合版本管理。因此，我们通过运行一个 Run Script 的 Build Phase 来管理、下载这些文件。在项目每次编译时，首先执行这个步骤，从而确保本地的二进制文件是最新的。 因此，这个脚本需要从一个项目文件读取一些信息，然后从服务器下载对应的个数不定的文件，而这些文件后面会作为 On-Demand Resources 打包进 app bundle。 WWDC22: Demystify parallelization in Xcode builds | Apple 介绍了新的现代构建系统通过一些巧妙的办法，最大程度并行化编译过程，以节省时间。不得不说，看了视频里展示类似于火焰图的性能图表，所有构建流程都紧凑地分散在不同的物理核心上时，令…  ( 3 min )

Whenever I get a new machine, reinstall my system, or start at a new workplace with a freshly installed IntelliJ IDEA, there are a few key settings I always configure right away. They save time, reduce friction, and help me stay focused on writing code instead of fighting the IDE. Auto Import on the Fly In the past, I used to lose precious minutes manually importing every missing package — especially when pasting code snippets from colleagues or external sources. Enabling “Auto-import on the fly” ensures that IntelliJ automatically takes care of import statements as I write code. It might seem like a small thing, but over the course of a day (or sprint), it adds up to a lot of saved time and fewer frustrating interruptions. 👉 Settings → Editor → General → Auto Import →Optimize imports …  ( 4 min )

Today was a massive win for Story Hero — we officially launched our first landing page at https://storyhero.site! 🚀 We built and shipped the landing page in record time using React inside Bolt.new, took inspiration from 21st.dev, and deployed via Netlify. Then we claimed our free custom domain using Entri (IONOS) — and just like that, Story Hero was live. It’s: 🔄 Responsive & mobile-friendly 💫 Full of subtle animations 🔍 SEO-optimized with OG metadata 📬 Equipped with an email waitlist signup Honestly, it turned out beautiful and exceeded our expectations — and it’s already helping us tell the Story Hero story to the world. We also whipped up our first draft of App Store screenshots. They’re rough, but they’re enough to help us push towards our next big milestone: getting the app submitted for App Store review ASAP. The review process can take time (and surprises happen), so our focus is to get a "good enough" build live fast, then iterate from there. The sooner we get it into Apple’s hands, the sooner we can get real users and even paying subscribers — all before the hackathon ends. This week’s progress gets us one step closer to the goal: launching a real product with paying users in just 30 days. We’re still going for the “Make More Money” challenge, and every decision is focused on that north star. Even if we don’t win a prize, building Story Hero alongside this community is already worth it. Let’s keep shipping. – Josh & Daniel Team Story Hero Story Hero What is Story Hero?

The Opensearch folks who extended Elasticsearch are not stupid – that's why determining how one stores data in an OS Cluster is an index-level configurable setting, not one flat setting to apply throughout. Which puts the onus on us – to determine the most efficient, cheapest and fastest way to store data – for every different index. If you have enough unused-compute in your OS Nodes, below are perhaps the best compression algorithms to use for your usecases when you know the read and write patterns to your index. Let's look at the why: Frequent Writes, Frequent Reads: zstd_no_dict Reasoning: This codec offers the best write performance and very good read performance. Since both reads and writes are frequent, prioritizing speed is crucial. While compression is slightly less than zstd, t…  ( 7 min )

A while ago, I had the opportunity to lead a practical session with a few of my students, where we explored the power and flexibility of Wazuh—a free, open-source security platform offering extended detection and response (XDR) and SIEM capabilities. The goal of the session was to help them understand how Wazuh can be used to monitor system integrity, detect malware, and centralize security operations. Here's a detailed breakdown of what we covered during the lab: We started with deploying Wazuh and installing its agent on both Kali Linux and Windows OS systems in our lab environment. The students learned how to ensure the agent is properly connected and visible within the Wazuh dashboard. One of the key things I emphasized was the importance of SSH access to the Wazuh server.

AI is beginning to reshape the estate planning field, streamlining routine processes and shifting how attorneys deliver value to clients. While the human element remains central to this deeply personal area of law, AI is enhancing how attorneys operate—both behind the scenes and at the client-facing level. Key Ways AI Is Impacting Estate Planning Attorneys: Client Intake and Communication Some firms are using AI chatbots or guided questionnaires to collect initial client information, identify goals, and flag common issues. This reduces administrative work and helps attorneys begin each case with clearer context. Risk Detection and Compliance AI tools can now analyze estate documents for errors, inconsistencies, or missing provisions. This adds a layer of quality control and helps attorneys ensure documents align with a client’s objectives and current laws. Educational Tools and Client Empowerment AI-driven platforms can also help clients understand complex concepts like probate, trust funding, or tax exposure—making the attorney’s job easier and consultations more productive. AI isn’t replacing estate planning attorneys—it’s refining their role. By automating routine tasks, attorneys can focus on personalized strategies, complex family dynamics, and providing the human guidance that clients still deeply value.

Use your own machine to validate your MVP When you're bootstrapping a project or simply want to validate an MVP without burning cash on infrastructure, most MVPs don't need a VPS. I just needed a URL I could share, fast. That’s exactly what I did to get DevScout online and test the MVP. In this article, I’ll explain how I used my own computer as a server, combined with Cloudflare Tunnel, to make the app publicly accessible, allowing me to test everything end-to-end, gather feedback, and only later invest in a proper VPS. Simple: I didn’t want to spend money before proving the idea had potential. Even cheap VPS options can be overkill when you're still building and validating your minimum viable product.

Yesterday, Apple dropped something unexpectedly beautiful at WWDC 2025. While we were all waiting for the next AI breakthrough, Tim Cook surprised everyone with iOS 26, featuring the new "Liquid Glass" design language. The design refresh is inspired by Apple's VR headset, the Vision Pro, bringing translucent menus, glossy icons and rounded controls across all Apple devices. But here's the thing about us developers – when Apple shows us something shiny and new, we can't help but think: "I bet I could build that with CSS." 🤓 So naturally, instead of waiting for iOS 26, I decided to recreate Apple's Liquid Glass effect using nothing but HTML and CSS. No JavaScript, no complex frameworks – just good old-fashioned web magic. Apple's Liquid Glass uses real-time rendering and dynamically reacts …  ( 5 min )

Hello 👋! So, yesterday, I released pride-rs to allow Rustaceans to easily add pride flags to their landing pages. But then I thought, "Hmm. This is nice, but it's not nearly gay enough." There was no theatrical entrance, no bright attractiveness, no Ferris the crab doing a dance move on a Progress Pride flag. So obviously, I needed to take things to the next level. I should push it to the absolute extreme. I needed to put flags somewhere big, bold, fabulous, and meaningful. Naturally, I used hero crate: a package for making hero sections in WASM: and decided it was time to inject it with unapologetic queer energy.

AWS continues to expand its offer of resource visibility with enhanced security. The newest addition to the arsenal is the integration between AWS Resource Explorer and AWS PrivateLink, now available in all commercial regions. This move marks an important step for organizations that need to locate resources broadly, but without giving up private traffic, especially in environments with tighter security restrictions. Resource Explorer alone represents a breakthrough in the way administrators view their resources spread across different accounts and regions. Now, with support for PrivateLink, this capability can be achieved within the scope of VPC, without the need to expose calls to the public Internet. This type of evolution addresses a sensitive point in multi-account architectures: how to ensure that distributed teams have visibility over the environment without compromising private connectivity standards? The new integration solves precisely this dilemma. It enables broad searches for resources using the Console, CLI, or SDKs, all encapsulated within the private VPC fabric. In practice, this means that it is possible to consult resources on an organizational scale, with enhanced security and without relying on public routes. The experience is still accessible via the unified search bar, which maintains operational fluidity even in environments with tighter governance. The big advantage here is not just in the discovery itself, but in the way this discovery is made. By keeping traffic within the PrivateLink domain, the risk of exposing sensitive metadata and API calls is drastically reduced. This control is essential for companies that need to meet more demanding compliance requirements, especially in sectors such as finance, healthcare, or government. With this update, Resource Explorer takes another leap towards becoming not just an inventory tool, but a central point of contextual visibility, and now more compatible with corporate security policies. I hope you enjoyed it! See you next time.  ( 3 min )

Have you ever encountered an error when trying to run the npm install command, also known as npm i, and the process simply doesn’t work as expected? This type of problem is more common than it seems and can arise for several reasons, such as incorrect environment configurations, system permissions, or even issues related to conflicting dependencies. In this article, we will explore the most common causes of this error and, most importantly, how to fix it so you can get back to development without any more issues. This happens due to the PowerShell execution policy settings. Here is a step-by-step guide to resolve the problem: 1- Open PowerShell as Administrator: ● Search for "PowerShell" in the Start menu. ● Right-click on "Windows PowerShell" and select "Run as administrator." 2-Change the Execution Policy: In PowerShell, type the following command to allow the execution of scripts: Set-ExecutionPolicy RemoteSigned Press "Enter" and, when prompted, type "Y" to confirm the change. 3- Check the Execution Policy: To make sure the change was applied correctly, run the following command: Get-ExecutionPolicy It should return the RemoteSigned policy, which allows local scripts and remote scripts that are signed to run. 4- Run the npm install Command Again: Now, you can try running the command again: npm create vite@latest This should resolve the script-blocking issue and allow the installation to complete successfully. Reverting to the Default Policy (Optional): If you prefer to revert the execution policy to the more secure default after the installation, just run the following command: ⚠️ Important: Always be cautious when changing the execution policy. Only run scripts from trusted sources. To revert to the default policy, use the following command: 🚨 The last command npm create vite@latest is only needed if you are using vite.

Você já se deparou com algum erro ao tentar rodar o comando npm install, também conhecido como npm i, e o processo simplesmente não funciona como esperado? Esse tipo de problema é mais comum do que parece, e pode surgir por diversos motivos, como configurações incorretas do ambiente, permissões de sistema ou até questões relacionadas a dependências conflitantes. Neste artigo, vamos explorar as causas mais frequentes desse erro e, o mais importante, como corrigi-lo para que você possa voltar ao desenvolvimento sem mais problemas. Isso acontece devido às configurações de política de execução do PowerShell. Aqui está um guia passo a passo para resolver o problema: Abra o PowerShell como Administrador: ● Pesquise por "PowerShell" no menu Iniciar. ● Clique com o botão direito em "Windows PowerShell" e selecione "Executar como administrador". Altere a Política de Execução: No PowerShell, digite o seguinte comando para permitir a execução de scripts: Set-ExecutionPolicy RemoteSigned Pressione "Enter" e, quando solicitado, digite "Y" para confirmar a alteração. Verifique a Política de Execução: Para garantir que a alteração foi feita corretamente, execute o comando: Get-ExecutionPolicy Ele deve retornar a política RemoteSigned, que permite a execução de scripts locais e de scripts remotos que sejam assinados. Execute o Comando npm installNovamente: Agora, você pode tentar rodar o comando novamente: npm create vite@latest Isso deve resolver o problema de bloqueio de scripts e permitir que a instalação seja concluída com sucesso. Revertendo para a Política Padrão (Opcional): Se você preferir reverter a política de execução para o padrão de segurança mais rígido após a instalação, basta rodar o comando: ⚠️ Importante: Sempre tenha cuidado ao alterar a política de execução. Execute apenas scripts de fontes confiáveis. Para reverter para a política padrão, use o seguinte comando. Set-ExecutionPolicy Restricted 🚨 Esse ultimo comando npm create vite@latestseria somente no caso de você estiver usando vite Fonte: Link  ( 3 min )

trap. Long before the term “social engineering” became common cybersecurity jargon, a simple email with the subject line “ILOVEYOU” blindsided millions. What looked like a harmless confession of affection turned out to be one of the most devastating and cunning malware attacks in history. This is the story of the LoveLetter virus: the digital Romeo with a payload of chaos.

Understand how ClusterIP routes traffic in Kubernetes, learn from real-world production failures, and fix them like a pro. This guide covers everything from kube-proxy internals to service misconfigurations and observability. ClusterIP is the default service type in Kubernetes. It enables intra-cluster communication by exposing a virtual IP address that distributes traffic to backend pods. But when things break in production, understanding how ClusterIP works internally is essential to resolving outages fast. This guide walks you through the ClusterIP traffic flow, and shares two real-world production issues, including how they were detected and fixed.

Overview Plotting is one of those things you don't really care about until you need it. For that reason, working on plotting isn't exciting - but not having it can be really annoying. The goal of the plotting API in Divooka is to provide a very high-level, easy-to-use (ideally single-node) setup for common plot types: you just supply the source data, pick the plot type, behold and voila - you get the resulting chart. In the case of the Plotting toolbox, the results are static images. This scheme allows some fairly complex plot types, as seen here: However, things can become tricky when we want to support advanced style configurations, for which the convention is to expose data on a node as direct inputs and style configurations as a separate Configurations input, as discussed in this b…  ( 5 min )

In the past, when I opened Excel, it just looked like an empty grid — rows, columns, cells, and tables. It felt dry and technical, like a digital notebook without much purpose. But once I began learning data analysis, I quickly realized Excel is far more than a basic spreadsheet tool. It's one of the most accessible and powerful platforms for working with data — especially when you're just starting out. So, What Is Excel Really? It’s part calculator, part notebook, part detective. And with just a few key skills, Excel becomes your go-to tool for understanding what your data is really saying. 💼 Real-World Uses of Excel in Data Analysis HR Analytics: Understanding People Through Data HR teams do more than just handle hiring paperwork. They use data to improve employee experiences and workplace performance. Example: Example: Healthcare Data: Improving Efficiency While Excel doesn’t replace hospital systems, it’s incredibly useful for managing non-sensitive healthcare data like appointments, staff schedules, or treatment plans. Example: 🔍 Excel Features I’ve Come to Love VLOOKUP: A lifesaver when combining datasets. I’ve used it to match product names with IDs or to connect survey results with demographic info. Conditional Formatting: This makes patterns jump off the page — like highlighting overdue tasks, duplicate entries, or high scores. IF Statements: Great for applying logic and flagging data — for example, labeling rows as “Pass” or “Fail” based on a score. 💭 How Excel Changed the Way I See Data But now? I see data as a conversation. When I open a dataset, I instinctively ask: More importantly, Excel has made me more careful. I’ve learned to look twice before jumping to conclusions, and I’ve gained a deep appreciation for how a simple tool can surface powerful insights.  ( 4 min )

In the previous article we discussed how to assemble a docker container and run it. In this article, we will go further and talk about such a thing as Kubernetes. Kubernetes Kubernetes is a tool for orchestrating(managing) docker containers. With this tool you can deploy, scale and manage your containerized apps. Kubernetes commonly used in developing and production. Imagine you have a web application made up of multiple components: a frontend, a backend, and a database. Deploying and managing these parts manually, especially when they need to scale or recover from crashes, can become time-consuming and error-prone. Kubernetes automates this process, ensuring your application stays healthy and performs well. Manifest manifest is a YAML file that describes the desired state of a Kubernetes …  ( 5 min )

One thing I learned about: Web3 domain services Blockchain addresses are not intuitive for everyday users. Web3 domain services provide memorable names tied to on-chain accounts. This is similar to how DNS resolves domain names into IP addresses. This should help Web3 users own a domain and send/receive transactions. But, there are adoption challenges. Examples: ENS Unstoppable Domains Solana Name Service Handshake Tezos Domains Each service resolves domains only within a set of networks but not in others. This is bad because... Users need to register their domain at each network Domains can collide with each other They use the default DNS servers of the operating system or the browser. The only partial exception is Brave, which resolves some domains (e.g. .crypto, and .eth) While you can set up a custom Web3 DNS resolver, you cannot expect every visitor of your Web3 domain to do the same.

In a NoSQL database, data structure varies based on requirements. In a List, data is stored in a specific order, and the position of each element matters. For example, to access the first element in a List, you retrieve the value at index 0, which is predictable due to the ordered nature of Lists. However, when the order of data is not important, a Dictionary (or key-value store) is more suitable. Consider a scenario where you need to store user information like age, address, first name, and last name. In this case, the sequence of these fields doesn’t matter. With a Dictionary, you can directly access a specific value using its key, such as retrieving the first name by querying the "first_name" key, without needing to know the last name or other fields. Key differences: In a List, values are stored with predefined, sequential indices (0, 1, 2, ...), and you access data by its position. In a Dictionary, you define custom keys mapped to values, allowing direct access to data via the key, regardless of order. Thus, for scenarios where you need flexible, key-based access to data without relying on order, a Dictionary is the preferred choice. Coffee Menu in Python — Dictionary Operations Creating a Coffee Menu (Dictionary) print(coffee_menu) Accessing a Value (Using Key) print(coffee_menu['Espresso']) Output: Bold shot! Changing a Value coffee_menu['Espresso'] = 'Tiny Thunder' print(coffee_menu) Output: Iterating Over the Dictionary Only Keys Output: Keys and Values (Method 1) Keys and Values (Method 2) Adding an Item Removing Items Using pop(key) coffee_menu.pop('Espresso') print(coffee_menu) Output: Using popitem() Removes the last inserted item. Example Output: ⚠️ Note: If the dictionary is empty, popitem() will raise a KeyError. Using del Statement del coffee_menu["Latte"] print(coffee_menu) 📝 Note: Each operation was done individually for demonstration, so dictionary contents might look different in each output. In a real program, you'd typically chain these actions as needed.  ( 4 min )

Hello guys and welcome to my devblog where I've been documenting my journey as I develop my ambitious package manager called "deadlock" and today was again a frustrating day for me as I had to install the zlib library to the project and just like always, it didn't build in the first time. If you've been following this series, you'd know that installing a library in C++ is as hard as a wooden stick. It won't build until I RECONFIGURE THE WHOLE SH*T FROM GROUND UP. Anyways, after the reconfigure, I saw some weird decisions I had made throughout the whole process like why did I use FetchContent to download the libraries on the fly when I had already put them in my source folder. I could've just included the subdirectory at the build time. At this point I realised a basic rule of programming: and then I ignored all of it and went ahead to read the documentation of zlib. I am currently reading this and I hope it is at least half if not as completely easy as the JSON one. That's all for today guys, will catch you tomorrow when I bring updates about this library.

In JavaScript, variables can be declared using var, let, or const. Though they all serve the same fundamental purpose—declaring variables—they behave quite differently in terms of scope, hoisting, reassignment, and more. Let’s break down their key differences. Feature var let const Scope type Function-scoped Block-scoped Block-scoped var – Function Scope Variables declared with var are function-scoped, which means they are only accessible inside the function in which they are defined. function example() { if (true) { var x = 10; } console.log(x); // ✅ 10 - accessible because var is function-scoped } let and const – Block Scope Both let and const are block-scoped, meaning they only exist within the enclosing {} block. function example() { if (true) { let y = 20; const z = 30; } console.log(y); // ❌ ReferenceError console.log(z); // ❌ ReferenceError } var is hoisted and initialized. console.log(a); // ✅ undefined var a = 5; let and const are hoisted but not initialized console.log(b); // ❌ ReferenceError (TDZ) let b = 10; var allows redeclaration and reassignment var x = 1; var x = 2; // ✅ No error x = 3; // ✅ No error let allows reassignment but not redeclaration let y = 1; let y = 2; // ❌ SyntaxError y = 3; // ✅ Allowed const allows neither const z = 1; const z = 2; // ❌ SyntaxError z = 3; // ❌ TypeError The Temporal Dead Zone (TDZ) is the period between entering the scope and the actual declaration where variables declared with let and const cannot be accessed. function test() { console.log(a); // ❌ ReferenceError (TDZ) let a = 10; } With var, accessing the variable before the declaration just returns undefined, but with let and const, it throws an error due to the TDZ.  ( 4 min )

Java handles memory management differently for static and instance variables. Static variables are stored in the method area and belong to the class, meaning they are shared among all instances. They are loaded into memory only once when the class is first loaded. In contrast, instance variables are stored in the heap and are unique to each object, getting created each time an object is instantiated. This clear separation helps Java manage memory efficiently and reduces redundancy. Understanding this distinction is vital for writing optimized programs.

TLDR: dans le monde du recrutement tech, les entreprises recherchent des experts d’un outil ou framework spécifique (Symfony, Nest, React, Angular...), au lieu de rechercher des développeurs capables de résoudre des problèmes métier. Cet article explore pourquoi cette approche purement technique est limitée et comment des principes issus du TDD (Test-Driven Development) et de la clean architecture permettent de concevoir des applications solides, en se concentrant sur ce qui génère réellement de la valeur ajoutée pour une entreprise : son coeur de métier. C'est le genre d'annonce qui est malheureusement devenu monnaie courante dans un monde de la tech en pleine crise. Elle reflète une fâcheuse tendance à privilégier des compétences techniques spécifiques, souvent au détriment d’une vérita…  ( 9 min )

While Solana has long been celebrated for its impressive base-layer performance, processing thousands of transactions per second, the blockchain landscape of 2025 demands even greater scalability. The emergence of sophisticated Layer 2 solutions marks a pivotal evolution in Solana’s architecture, challenging the conventional wisdom that high-performance chains don’t need additional scaling layers. This transformation comes as Solana has secured its position as the second-largest blockchain by Total Value Locked (TVL), trailing only Ethereum. The integration of Layer 2 protocols isn’t just about increasing transaction throughput — it’s about creating specialized processing environments that cater to specific use cases while maintaining the network’s core advantages. Current Solana Layer 2 L…  ( 7 min )

In part 1 of this series, I introduced some of the most common Day 2 serverless operations, focusing on Function as a Service. In this part, I will focus on serverless application integration services commonly used in event-driven architectures. For this post, I will look into message queue services, event routing services, and workflow orchestration services for building event-driven architectures. Message queues enable asynchronous communication between different components in an event-driven architecture (EDA). This means that producers (systems or services generating events) can send messages to the queue and continue their operations without waiting for consumers (systems or services processing events) to respond or be available. Security should always be the priority, as it pro…  ( 7 min )

Programming Practices Array Traversal Level: Requirement Description: For array traversal, prioritize using Array object methods such as forEach(), map(), every(), filter(), find(), findIndex(), reduce(), and some(). Negative Example: const numbers = [1, 2, 3, 4, 5]; const increasedByOne: number[] = []; for (let i = 0; i num + 1); Level: Requirement Description: Avoid performing assignments in control - flow expressions used in if, while, for, or ?: statements, as this can lead to unexpected behavior and poor code readability. Negative Example: if (isFoo = false) { // ... } Positive Examp…  ( 4 min )

Terraforming the Voice: Deploying a Clone Application with Infrastructure as Code on AWS By Todd Bernson, CTO of BSC Analytics, Terraform Whisperer There’s something beautiful about watching an entire production-grade environment spring to life from a single command — like watching a barbell float off the ground when the form is just right. This article is for those of us who believe that if your infrastructure isn’t defined in code, it’s one rogue click away from disaster. Welcome to the story of how I built and deployed a self-hosted voice cloning application on AWS using Terraform for full-stack automation. We’re not talking about a toy project or an ML demo in a Jupyter notebook — this is a fully containerized, production-ready, auto-scaling, API-driven platform running in the cloud, d…  ( 5 min )

Introduction Claude Code has been getting a lot of attention lately. I've been following its increase of the youtube mindshare, and I finally decided I needed to try it out for myself. Since I've been using Cursor so heavily, I was curious about what value Claude Code actually provided: how I would incorporate it into my workflow and if it complimented or replaced Cursor. The topic of combining Claude Code with Cursor has been covered in some new videos in the past week, and I watched each of these: This Cursor Setup Changes Everything (Claude Code) Claude Code + Cursor AI = Vibe Coding Paradise Each video is interesting and informative in its own right. This is where I learned that Claude Code was now offered as part of their subscription plans, and is no longer limited to the metere…  ( 8 min )

Programming Practices Class Property Access Modifiers Level: Recommendation Description: ArkTS provides private, protected, and public access modifiers for class properties. The default access modifier is public. Using appropriate access modifiers can enhance code security and readability. Note that if a class contains private properties, the class cannot be initialized using object literals. Negative Example: class C { count: number = 0; getCount(): number { return this.count; } } Positive Example: class C { private count: number = 0; public getCount(): number { return this.count; } } Level: Recommendation Description: In ArkTS, floating - point values include a decimal point, but there is no requirement for a digit before or after the decimal point. Adding digits both before and after the decimal point can improve code readability. Negative Example: const num = .5; const num = 2.; const num = -.7; Positive Example: const num = 0.5; const num = 2.0; const num = -0.7; Level: Requirement Description: In ArkTS, Number.NaN is a special value of the Number type used to represent non - numeric values. In ArkTS, Number.NaN is unique in that it does not equal any value, including itself. Comparisons involving Number.NaN are counterintuitive: both Number.NaN !== Number.NaN and Number.NaN != Number.NaN evaluate to true. To check if a value is Number.NaN, always use the Number.isNaN() function. Negative Example: if (foo == Number.NaN) { // ... } if (foo != Number.NaN) { // ... } Positive Example: if (Number.isNaN(foo)) { // ... } if (!Number.isNaN(foo)) { // ... }  ( 3 min )

Spacing and Code Style Guidelines Highlighting Keywords and Important Information with Spaces Level: Recommendation Description: Use spaces to highlight keywords and important information while avoiding unnecessary spaces. Follow these general guidelines: Add a space between keywords like if, for, while, switch and the left parenthesis (. Do not add a space between the function name and the left parenthesis ( in function definitions and calls. Add a space between keywords like else or catch and the preceding right brace }. Add a space before any opening brace {, except in the following cases: When an object is the first parameter of a function or the first element of an array, no space is needed before the object. For example: foo({ name: 'abc' }). In templates, no space i…  ( 5 min )

The Plot Twist Nobody Saw Coming This morning, Reuters dropped a bombshell that has every developer, AI researcher, and tech executive doing a double-take. OpenAI—the company behind ChatGPT that's been going head-to-head with Google in the AI race—just signed a deal to use Google Cloud for their computing needs. Let me repeat that: The company whose ChatGPT is the biggest threat to Google Search in decades is now paying Google for cloud infrastructure. If you're scratching your head thinking "wait, what?", you're not alone. This is like Apple deciding to manufacture iPhones in Samsung factories. But here's the thing—when you dig deeper, this move actually makes perfect sense from a technical perspective. Here's what most people don't realize about AI companies: they're absolutely starvi…  ( 7 min )

There was a time when the moon meant something more than a backdrop. It guided sailors, marked seasons, carried stories before books were written. Now, it sits inside phone screens, captured but rarely noticed. We track its orbit with precision, but when was the last time we truly saw it? Not through a lens. Not for a post. Just looked up and listened. Technology gives us more ways to observe, but observation is not meaning. Some symbols endure, even as their relevance fades. The moon waits, rising without applause, reflecting light without demand. Maybe it still belongs to strangers. Maybe that is what keeps it alive. Read full article here  ( 3 min )

We've all been there. You've built an amazing TypeScript project, spent weeks perfecting the code, and then... you need to document it. 😅 The README sits there, mocking you with its emptiness. Your functions are clean, your types are perfect, but explaining what everything does? That's going to take hours. What if I told you there's a tool that can analyze your entire codebase and generate beautiful, professional documentation in minutes? Let me introduce you to Syntax Scribe. Before we dive in, let's be honest about documentation: ✅ We know it's important ✅ We know our users (and future selves) need it ❌ We rarely have time to write it properly ❌ Keeping it updated is a nightmare ❌ Writing good docs is genuinely hard I used to spend entire weekends writing documentation for client proje…  ( 6 min )

Howdy! Ever since I discovered GitOps, I've been in love with the concept. The idea of managing all your infrastructure configuration from a centralized Git repository - and having a tool automatically apply those changes - is incredibly powerful. GitOps brings together Infrastructure as Code (IaC) and Continuous Integration/Continuous Deployment (CI/CD) in a seamless, declarative workflow. It's the ideal way to manage a Kubernetes cluster. In the past, I've used Flux to implement GitOps, but I've always been curious about ArgoCD. After hearing so many good things about it, I decided it was finally time to give it a try - and this project was the perfect opportunity. ArgoCD is a declarative GitOps continuous delivery tool for Kubernetes. It follows the GitOps pattern of using Git repositor…  ( 5 min )

Surviving Extreme Programming: A Developer's Wild Ride Have you ever wanted to strap your coding practices to a rocket and send them to the moon? That is what Extreme Programming (XP) does to traditional software development. As a developer who has been through the XP wringer, I am here to tell you it is both terrifying and exhilarating - like riding a rollercoaster built by the same people who review your pull requests. Extreme Programming is like regular programming, but after it's chugged five espressos. It takes good engineering practices and cranks them up to eleven. Think of it this way: If traditional development is like carefully planning a road trip with maps and hotel reservations, XP is more like deciding to drive cross-country with only a compass, a full tank of gas, and the …  ( 6 min )

This tutorial was written by Rajesh Nair. Java developers and MongoDB are like Aladdin and the Genie from Arabian Nights. Developers rub the lamp with their wildest NoSQL wishes, and MongoDB swoops in, granting Spring Boot microservices and REST APIs the magic they need to soar. But every so often, a Jafar-like menace swoops in, forcing our Aladdin (Java devs) to wrestle with sleepless nights. One such villainous foe is the connection timeout, locking APIs in a cave of wonders with no escape, leaving developers yearning for a magic carpet fix. So, what’s a connection timeout error? Imagine Aladdin, the developer, sending Abu, his trusty monkey, to fetch a shiny treasure—data—from MongoDB’s palace vault. Abu’s got 30 seconds to scamper over and back. But if the palace is packed with guards …  ( 13 min )

Debugging failing tests can be time-consuming and frustrating—especially when error messages are long or snapshot diffs are difficult to interpret. With the latest AI-powered tools in Playwright, resolving test failures has become significantly faster and more intuitive. Consider a basic Playwright test that uses snapshot testing to verify that the content inside getByRole('main') matches a previously stored snapshot. The snapshot might contain two distinct headings, for example. If the heading level in the application is changed—from to —the test fails, as expected, due to a mismatch with the stored snapshot. Traditionally, resolving this would involve reading the stack trace, analyzing the diff, and manually updating the test or snapshot. Playwright’s AI integration streamlines …  ( 4 min )

Como verificar e gerenciar serviços no Linux (Red Hat) Se você trabalha com servidores Linux, em especial Red Hat ou semelhantes como CentOS ou Rocky Linux, é essencial saber lidar com serviços em execução. Preparei comandos simples para identificar serviços ativos, liberar portas desnecessárias e evitar problemas de segurança. 📌 Verificando serviços ativos No Linux com systemd, usamos o comando systemctl: Listar todos os serviços ativos: systemctl list-units --type=service Ver status de um serviço específico (ex: Apache, MySQL): systemctl status mysqld.service Ver serviços configurados para iniciar no boot: systemctl list-unit-files --type=service 🔍 Verificando serviços escutando em portas de rede Para identificar portas abertas, use o comando ss (substituto do netstat): Ver portas abertas: ss -tuln Ver processos escutando em cada porta: ss -tulnp Alternativa com netstat (se instalado): netstat -tulnp 🛑 Parar e desabilitar serviços não utilizados Serviços desnecessários consomem recursos. Para desativá-los: systemctl stop nome-do-serviço systemctl disable nome-do-serviço Exemplo: Parando o Mysql systemctl stop mysqld.service systemctl disable mysqld.service ⚙️ Automatizando verificações Crie um script em Bash para agilizar verificações: #!/bin/bashecho "Serviços ativos:" systemctl list-units --type=service echo "Portas escutando:" ss -tulnp Dica: Agende com cron ou execute manualmente. 📌 Notas: Use sudo se necessário para comandos privilegiados.  ( 3 min )

Debouncing is a foundational technique in front-end development, especially when working with high-frequency events like user input. It helps control the rate of function calls, ensuring that performance-intensive operations — such as server requests — don’t trigger excessively as users interact with the UI. A classic example is a search bar: as the user types, the application waits until they’ve paused before sending a request to fetch matching results. Another familiar case is an autocomplete panel, where each keystroke could theoretically initiate a query — but shouldn’t. In Angular applications, especially those using the new reactive primitives introduced with Signals, developers often ask: “How do I debounce a signal?” At first glance, this might seem like a natural extension of reac…  ( 6 min )

Em maio de 2025, a OpenAI anunciou seu novo agente Codex, cujo diferencial é a execução paralela de tarefas, todas rodando diretamente na nuvem.

"Prop drilling" is a term in React (and other component-based UI frameworks) that describes the act of passing data down through multiple layers of nested components, even if the intermediate components don't actually need or use that data. They simply serve as conduits to pass the data further down the component tree until it reaches the component that actually needs it. Here's a breakdown of what it is, why it's a problem, and common solutions: What it is: App ├── ParentComponent │ ├── ChildComponent │ │ └── GrandchildComponent │ │ └── DeeplyNestedComponent (needs 'userData') If App has some userData that only DeeplyNestedComponent needs, you would have to pass userData as a prop from: App to ParentComponent ParentComponent to ChildComponent ChildCompon…  ( 5 min )

Web Workers and Service Workers are two critical technologies in web development for handling background tasks and offline caching. They differ significantly in their working principles and use cases. Web Workers enable compute-intensive tasks to run in a background thread, preventing the main thread (UI thread) from being blocked, thus improving page responsiveness. Below are the basic steps to create and use a Web Worker: Create a JavaScript file, such as worker.js, containing the code to be executed. // worker.js self.addEventListener('message', (event) => { const data = event.data; // Perform computation or other intensive tasks const result = heavyComputation(data); self.postMessage(result); // Send result back to the main thread }); In the main page’s JavaScript, instantiate…  ( 7 min )

React components, elements, and instances In React, a component is simply a function that returns a React element. Take a look at this example: const App = () => { return ( BHavesh Prajapati ); }; This component, App, returns a React element, which is an object referred to as an "instance". When this code is executed, console.log(App()), it shows the underlying structure of the returned object (or instance): { "$$typeof": Symbol(react.element), key: null, props: { children: "Bhavesh Prajapati" }, ref: null, type: "div", } Let’s break down this structure: $$typeof: It's an internal property used by React to identify React elements. type: The type of the element, in this case, it's a div. props: Properties of the element…  ( 4 min )

TL;DR: The OLTP/OLAP split no longer fits how developers build today. Postgres and the lakehouse are now used side-by-side – but stitched together with brittle pipelines. We think they belong in a single, modular system: open formats, bidirectional sync, and real-time performance by default. The architecture of modern data systems is undergoing a fundamental shift. Ask a developer how they build data systems today, and the answer increasingly looks like this: Postgres for the application, a lakehouse for the analytics and data science. Postgres, long favored for transactional workloads, has evolved into a general-purpose operational database. It’s trusted, flexible, and deeply extensible, powering everything from customer transactions and CRUD apps, to real-time dashboards and AI-backed pr…  ( 7 min )
